In Vim,
:echo system('cat - &', 'foo')
works because for both system() and :! Vim writes input to a temp file and uses
shell syntax to redirect the file to the backgrounded `cat` (get_cmd_output()
.. make_filter_cmd()).
In Nvim,
:echo system('cat - &', 'foo')
fails because we write the input directly via pipes (shell.c:do_os_system()),
but (per POSIX[1]) backgrounded process input stream is redirected from
/dev/null (unless overridden by shell redirection; supported only by some shells
[2]), so our writes are ignored, the process exits quickly, and if we are
writing data larger than the buffer size we'll see EPIPE.
This still works:
:%w !tee > foo1358.txt &
but this does not:
:%w !tee foo1358.txt &
though it *should* (why doesn't it?) because we still do the temp file dance
in do_bang() .. do_filter().

These tests are essentially affirming a regression vs Vim. In Vim,
:echo system('cat - &', 'foo')
returns "foo", because Vim internally wraps the command with shell-specific
syntax to redirect the streams from /dev/null[1].
That can't work in Nvim because we use pipes directly (instead of temp files)
and don't wrap the command with shell-specific redirection syntax.

The previous form was passing because it happens immediately before this form;
but on a very fast(?) server the screen check might miss that form. It's also
not really want we want to assert anyways.
this is consistent with vim, and is necessary for plugins that implement
their own input modes using "getchar()" and still want to do async
event processing.
Check `exists('b:term_title')` to avoid the BufReadCmd for already-initialized
:terminal buffers.
Move the test for `:argadd`.
Add a test for `:edit<CR>`.
Tweak comments and code style.
In order to provide better compatibility with the classic bindings, the
API needs to provide the ability to query the number (really index) of
the window/tabpage.
This is needed for neovim/python-client#87, as discussed in
neovim/neovim#1898.

`lib/queue.h` implements a basic queue. `event/queue.c` implements
a specialized data structure on top of lib/queue.h; it is not a "normal"
queue.
Rename the specialized multi-level queue implemented in event/queue.c to
"multiqueue", to avoid confusion when reading the code.
Before this change one can eventually notice that "macros (uppercase
symbols) are for the normal queue, lowercase operations are for the
multi-level queue", but that is unnecessary friction for new developers
(or existing developers just visiting this part of the codebase).
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.

Problem: syn-cchar defined with matchadd() does not appear if there are no
other syntax definitions which matches buffer text.
Solution: Check for startcol. (Ozaki Kiichi, haya14busa, closesvim/vim#757)

When running the tests in a contained environment, the lingering
terminal processes prevent the unmounting of the filesystems in the
contained environment.
These tests fail on master, so it's not a regression. Changes in #4874
(parent commit) seem to work (and pass most CI), so skipping these tests
is better than blocking the changes.
Closes#5291
Restores behaviour identical to Vim. If the user calls the VimScript
function 'getcwd()' and the working directory cannot be found (for
example because the directory has been deleted since the last time it
was used) an empty string needs to be returned instead of throwing an
error.
