In #8226 <A-x> and <M-x> were changed to behave like <Esc>x in insert
mode when no mapping exists. This commit backs out that change and
replaces it with a more general one that makes unmapped ALT and META
keypresses as <Esc>+char in all modes. This fixes an unnecessary and
confusing inconsistency between modes.
Traditionally, when navigating to a specific location from the middle of
the jumplist results in shifting the current location to the bottom of
the list and adding the new location after it. This behavior is not
desireable to all users--see, for example
https://vi.stackexchange.com/questions/18344/how-to-change-jumplist-behavior.
Here, another jumplist behavior is introduced. When jumpoptions (a new
option set added here) includes stack, the jumplist behaves like the
tagstack or like history in a web browser. That is, when navigating to
a location from the middle of the jumplist
2 first
1 second
0 third <-- current location
1 fourth
2 fifth
to a new location the locations after the current location in the jump
list are discarded
2 first
1 second
0 third
<-- current location
The result is that when moving forward from that location, the new
location will be appended to the jumplist:
3 first
2 second
1 third
0 new
If the new location is the same
new == second
as some previous (but not immediately prior) entry in the jumplist,
2 first
1 second
0 third <-- current location
1 fourth
2 fifth
both occurrences preserved
3 first
2 second
1 third
0 second (new)
when moving forward from that location.
It would be desireable to go farther and, when the new location is the
same as the location that is currently next in the jumplist,
new == fourth
make the result of navigating to the new location by jumping (e.g. 50gg)
be the same as moving forward in the jumplist
2 first
1 second
0 third
1 new <-- current location
2 fifth
and simply increment the jumplist index. That change is NOT part of
this patch because it would require passing the new cursor location to
the function (setpcmark) from all of its callees. That in turn would
require those callees to know *before* calling what the new cursor
location is, which do they do not currently.

In #6221 there was a mistake in calculating which folds need to be
re-ordered. When there are no folds after those that have been adjusted,
then `move_end` remains 0. This results in reverse_fold_order()
swapping folds that have been adjusted with uninitialised folds in the
remainder of the grow array.
Add a check in foldMoveRange() to account for this case.
Hope this will make people using feed_command less likely: this hides bugs.
Already found at least two:
1. msgpackparse() will show internal error: hash_add() in case of duplicate
keys, though it will still work correctly. Currently silenced.
2. ttimeoutlen was spelled incorrectly, resulting in option not being set when
expected. Test was still functioning somehow though. Currently fixed.
When foldUpdateIEMSRecurse() re-uses an existing fold, it misses the
case where the existing fold spans from before startlnum to after
firstlnum, the new fold does not span this range, and there is no
"forced start" of a fold. We add a case for this in.
Ensure that if there was no forced break in folds, we merge folds that
now touch each other.
Include testing for a tricky foldmethod=expr case that has never been a
bug. This case works at the moment because of some effects that are not
obvious when reading the code.
A test for this could be useful to ensure a regression doesn't happen.

In order to re-order marks according to the :move command, do_move()
uses mark_adjust() in a non-standard manner. The non-standard action is
that it moves some marks *past* other marks. This doesn't matter for
marks, but mark_adjust() calls foldMarkAdjust() which simply changes
fold starts and lengths and doesn't have enough information to know that
other folds have to be checked and reordered.
The array of folds for each window are assumed to be in order of
increasing line number, and if this gets broken some folds can get
"lost".
There has been a previous patch to avoid this problem by deleting and
recalculating all folds in the window, but this comes at the cost of
closing all folds when executing :move, and doesn't cover the case of
manual folds.
This patch adds a new function foldMoveRange() specifically for the
:move command that handles reordering folds as well as simply moving
them. Additionally, we allow calling mark_adjust_nofold() that does the
same as mark_adjust() but doesn't affect any fold array.
Calling mark_adjust_nofold() should be done in the same manner as
calling mark_adjust(), but according changes to the fold arrays must be
done seperately by the calling function.

Fix a problem when filtering manually folded lines
When foldMarkAdjustRecurse() is called to adjust folds that start inside
the range of lines that are being moved and end outside that range, it
calculates `amount_after` for its recursive call incorrectly.
The calculation assumes that folds inside the changed range are being
deleted, but this is not always the case.
This means nested folds that start after the changed range of lines are
shifted an incorrect amount.
We fix this by calculating the `amount_after` differently if the folds
inside the changed range are not being deleted.
Previously alternate branches were not accounted for properly, with this
change g- after an undo to a branch point works.
The current sequence number b_u_seq_cur is used in undo_time(), in
u_doit() this was calculated by subtracting one from the curhead
sequence number.
The curhead header entry represents the change that was just undone, so
the sequence number we want is that of the change we have moved to. This
is the sequence number of the undo head that is the uh_next element of
this curhead. That sequence number is not always one less than the
curhead sequence number -- there may have been an alternate branch at
this point.
Instead of subtracting one, we now directly find the sequence number of
curhead->uh_next.
Note some bugs were judged to have too ugly a fix to solve, tests to
demonstrate these problems, and the explanation behind not fixing them
are below.

-- The difficulty here is: The basic requirement is that the text

-- We can't add a count into the readbuf here because the insert mode
-- count is implemented with readbuf2 which is checked for characters
-- after readbuf1.
-- Hence, the ".gp command (which adds extra characters into readbuf1
-- to emulate leaving the cursor after the text by moving the cursor
-- after inserting the text) would insert the motion characters into
-- the buffer instead of using them to move after the insert has been
-- done.
-- I could probably get this working properly with a special flag put
-- into start_redo_ins() and set in do_put(), but I think this adds
-- much more complexity than fixing this bug justifies.

In Vim's main_loop function, the main loop is
while (!cmdwin
#ifdef FEAT_CMDWIN
|| cmdwin_result == 0
#endif
)
{
...
#ifdef FEAT_EVAL
/*
* May perform garbage collection when waiting for a character, but
* only at the very toplevel. Otherwise we may be using a List or
* Dict internally somewhere.
* "may_garbage_collect" is reset in vgetc() which is invoked through
* do_exmode() and normal_cmd().
*/
may_garbage_collect = (!cmdwin && !noexmode);
#endif
/*
* If we're invoked as ex, do a round of ex commands.
* Otherwise, get and execute a normal mode command.
*/
if (exmode_active)
{
if (noexmode) /* End of ":global/path/visual" commands */
return;
do_exmode(exmode_active == EXMODE_VIM);
}
else
normal_cmd(&oa, TRUE);
}
cmdwin_result is set to 0 before calling main_loop to handle the cmdwin
window and gets changed when the user causes a command to execute
(either through pressing <CR> or <C-c>). This means that when the
cmdwin isn't active OR the user is still editing their command,
main_loop runs and main_loop calls normal_cmd with toplevel true as long
as exmode isn't active.
When the normal mode state was extracted in dae006a9, the conditions for
toplevel and may_garbage_collect were combined. Since toplevel was set
to always ignore cmdwin, the v:count(1) variables were no longer being
updated when a command was prefixed with a count in the cmdwin.

It is otherwise impossible to determine which test failed sanitizer/valgrind
check. test/functional/helpers.lua module return was changed so that tests which
do not provide after_each function to get new check will automatically fail.
