- Much of the mouse chatter in gui.txt and term.txt is redundant; other
parts are outdated or irreleveant to Nvim.
- Fix default value of 'mousemodel' for Windows
Resets the TUI cursor color if:
- current 'guicursor' mode does not specify a highlight group
- cursor highlight group has "inverse" or "reverse" flag
- on Nvim exit
We interpret, "inverse" to mean "default cursor".
Example:
hi Cursor guifg=bg guibg=fg
set termguicolors
set guicursor=n-v-c-sm:block,i-ci-ve:ver25-Cursor,r-cr-o:hor20
* When the cursor shape is block, its color will be "inverse"
* When the cursor shape is I-beam, its color will be `hi Cursor`.
This is useful e.g. to prevent `set listchars=eol:¬` causing your cursor
color to a low contrast color in insert mode because you cursor are
often at EOL in insert mode.

After this change we never release blocks from memory (in practice it
never happened because the memory limits are never reached). Let the OS
take care of that.
---
On today's systems the 'maxmem' and 'maxmemtot' values are huge (4+ GB)
so the limits are never reached in practice, but Vim wastes a lot of
time checking if the limit was reached.
If the limit is reached Vim starts saving pieces of the swap file that were in
memory to the disk. Said in a different way: Vim implements its own
memory-paging mechanism. This is unnecessary and inefficient since the
operating system already has virtual memory and will swap to the disk if
programs start using too much memory.
This change does...
1. Reduce the number of config options and need for documentation.
2. Make the code more efficient as we don't have to keep track of memory
usage nor check if the memory limits were reached to start swapping
to disk every time we need memory for buffers.
3. Simplify the code. Once memfile.c is simple enough it could be
replaced by actual operating system memory mapping (mmap,
MemoryViewOfFile...). This change does not prevent Vim to recover
changes from swap files since the swapping code is never triggered
with the huge limits set by default.

fsync() is very slow on some systems. And since the parent commit, Nvim
is smarter about flushing files at certain times (e.g. CursorHold),
regardless of whether 'fsync' is enabled. So it's less risky to disable
'fsync'.
Profiling showed slow (2-4s) :write and :quit caused by fsync():
:quit
shada_write_file(NULL, false);

Wrapping a command in double-quotes allows cmd.exe to safely dequote the
entire command as if the user entered the entire command in an
interactive prompt. This reduces the need to escape nested and uneven
double quotes.
The `/s` flag of cmd.exe makes the behaviour more reliable:
:set shellcmdflag=/s\ /c
Before this patch, cmd.exe cannot use cygwin echo.exe (as opposed to
cmd.exe `echo` builtin) even if it is wrapped in double quotes.
Example:
:: internal echo
> cmd /s /c " echo foo\:bar" "
foo\:bar"
:: cygwin echo.exe
> cmd /s /c " "echo" foo\:bar" "
foo:bar
Currently writedelay shows the sequence of characters that are sent to
the UI/TUI module. Here nvim has already applied an optimization: when
attempting to put a char in a screen cell, if the same char already was
there with the same attributes, UI output is disabled. When debugging
redrawing it it sometimes more useful to inspect the redraw stream one
step earlier, what region of the screen nvim actually is recomputing
from buffer contents (win_line) and from evaluating statusline
expressions.
Take the popupmenu as an example. When closing the popupmenu (in the
TUI), currently 'writedelay' looks like vim only is redrawing the region
which the pum covered. This is not what happens internally: vim redraws
the entire screen, even if only outputs the changed region.
This commit allows negative values of 'writedelay', which causes a delay
for all redrawn characters, even if the character already was displayed
by the UI before.
Most fonts should have these by now. Both are a significant visual
improvement.
- Vertical connecting bar `│` is used by tmux, pstree, Windows 7 cmd.exe
and nvim-qt.exe.
- Middle dot `·` works on Windows 7 cmd.exe, nvim-qt.exe.
For reference: tmux uses these chars to draw lines: │ ├ ─

Get terminal debugging info by starting Nvim with 'verbose' level 3:
nvim -V3log
This is like Vim's `:set termcap`, which was removed in Nvim (and would
be very awkward to restore because of the decoupled UI).
The flag enables the current local directory set by ":lcd" to be saved
to views which is the current default behaviour. The option can be
removed to disable this behaviour.

- Prefer "TUI" where possible to refer to the host terminal.
- Remove obsolete tags and ancient TTY exposition.
- Establish "terminal" to consistently mean "terminal emulator" in all
Nvim documentation. This removes the need for verbose qualifiers in
tags and prose.
