Problem: No autocmd triggered in Insert mode with visible popup menu.
Solution: Add TextChangedP. (Prabir Shrestha, Christian Brabandt,

Fix that the TextChanged autocommands are not always triggered

OpenBSD's man returns all candidates when searching with -w instead of

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.
Remove "" from sys.path (typically the first entry), which could cause
e.g. "logging" to be added from the current directory.
This gets done already for loading the host in
runtime/autoload/provider/pythonx.vim.

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():

children_kill_cb() is racey. One obvious problem is that
process_close_handles() is *queued* by on_process_exit(), so when
children_kill_cb() is invoked, the dead process might still be in the
`loop->children` list. If the OS already reclaimed the dead PID, Nvim
may try to SIGKILL it.
Avoid that by checking `proc->status`.
Vim doesn't have this problem because it doesn't attempt to kill
processes that ignored SIGTERM after a timeout.

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
Update vim_diff.txt with :lmap differences, update documentation on
'keymap', and add tests.
The tests added are to demonstrate the behaviour specified in the

I have `g:python3_host_prog` set to the system Python, where a package
is also installed to provide the "neovim" module.
`:checkhealth provider` however displays a warning for this:
> Your virtualenv is not set up optimally.
This is because /usr/bin/python is not in /home/user/.pyenv.
I think this warning should not get displayed if host_prog_var exists.
It goes back to the initial commit (20447ba09), and is maybe only
missing the `!` there as with the previous commit.
Full output:
```

- Create a virtualenv specifically for Neovim and use `g:python3_host_prog`. This will avoid the need to install Neovim's Python module in each virtualenv.

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.

`g:loaded_python3_provider` gets set when the autoload file is sourced,
but this might error out, e.g. with deoplete:
[deoplete] Failed to load python3 host. You can try to see what happened by starting nvim with $NVIM_PYTHON_LOG_FILE set and opening the generated log file. Also, the host stderr is available in messages.
[deoplete] function remote#define#FunctionBootstrap[1]..remote#host#Require[10]..provider#pythonx#Require[13]..provider#Poll, line 14
[deoplete] deoplete requires Python3 support("+python3").
[deoplete] deoplete failed to load. Try the :UpdateRemotePlugins command and restart Neovim. See also :checkhealth.
It refers to `:checkhealth` from there explicitly, which would then
(without this patch) say that Python 3 is disabled.
This patch changes the reported info to include that it might have been
disabled due to some error, and keeps on going.
Only remove the directory contents. If the directory itself is removed,
then `sudo make install` creates a root-owned …/doc/ directory. That

If `jobstart()` fails, then the subsequent `rpcrequest()` will throw due
to an invalid channel id. This causes `job.stderr` not to exist, so we
throw another exception when trying to dump the job's stderr.

ci: install nodejs 8 in Appveyor, Travis
provider: check node version for debug support
Resolve https://github.com/neovim/neovim/pull/7577#issuecomment-350590592 for Unix.
provider: test if nodejs in ci supports --inspect-brk
nodejs host for neovim requires nodejs 6+ to work properly.
nodejs 6.12+ or 7.6+ is required for debug support via `node --inspect-brk`.
provider: run cli.js of nodejs host directly
npm shims are useless because the user cannot set node to debug mode via
--inspect-brk. This is problematic on Windows which use batchfiles and
shell scripts to compensate for not supporting shebang.
The patch uses `npm root -g` to get the absolute path of the global npm
modules. If that fails, then the user did not install neovim npm package
globally. Use that absolute path to find `neovim/bin/cli.js`, which is
what the npm shim actually runs with node. glob() is for a simple file
check in case bin/ is removed because the npm shims are ignored now.
Use `@cond <something>` to obscure a section from doxygen.
doxygen thinks kvec_withinit_t() is a function. That adds noise to the
generated API documentation, and also prevents the following function
from being noticed.

This is like Vim's `:set termcap`, which was removed in Nvim (and would
be very awkward to restore because of the decoupled UI).
ruby uses batchfiles with 'cmd' extension.
gem creates batchfiles with 'bat' extension.
`gem install rails` does the following in Windows (not Cygwin):
1. Run `gem.cmd install rails` on cmd.exe
2. gem.cmd runs `ruby.exe -x gem install rails`
3. `rails` gem is installed.
`rails.bat` is created in the same directory
where ruby.exe and gem.cmd reside.
Since "builtin" terminfo definitions were implemented (7cbf52db1b),
the decisions made by tui.c and terminfo.c are more relevant. Exposing
that decision in the 'term' option helps with troubleshooting.
Also: remove code that allowed setting t_Co. `:set t_Co=…` has never
worked; the highlight_spec test asserting that nvim_set_option('t_Co')
_does_ work makes no sense, and should not have worked.
