Extend the capabilities of is_os to detect more platforms such as
freebsd and openbsd. Also remove `iswin()` helper function as it can be
replaced by `is_os("win")`.
This is essentially a convenience wrapper around the `pending()`
function, similar to `skip_fragile()` but more general-purpose.
Also remove `pending_win32` function as it can be replaced by
`skip(iswin())`.
These were just added to avoid churn when changing the default
of 'display'. To simplify message handling logic, we might want
to remove support for printing messages in default_grid later on.
This would allow things like printing error messages safely in the
middle of redraw, or a future graduation of the 'multigrid' feature.
Remove the command('qall!') from mksession_spec.lua because it prevents
helpers.rmdir() from retrying.
Allow extra trailing spaces when matching terminal lines.
It is perfectly fine and expected to detach from the screen just by
the UI disconnecting from nvim or exiting nvim. Just keep detach() in
screen_basic_spec, to get some coverage of the detach method itself.
This avoids hang on failure in many situations (though one could argue
that detach() should be "fast", or at least "as fast as resize",
which works in press-return already).
Never use detach() just to change the size of the screen, try_resize()
method exists for that specifically.
REP_NODELAY was added because REP delayed too much. This changes REP to
only add a delay on every 100th line instead.
This helps to cover the additional pulse steps with
out_data_decide_throttle, which would have required to change
REP_NODELAY anyway.

warning: Screen changes were received after the expected state. This indicates
indeterminism in the test. Try adding screen:expect(...) (or wait()) between
asynchronous (feed(), nvim_input()) and synchronous API calls.
- Use screen:redraw_debug() to investigate; it may find relevant intermediate
states that should be added to the test to make it more robust.
- If the purpose of the test is to assert state after some user input sent
with feed(), adding screen:expect() before the feed() will help to ensure
the input is sent when Nvim is in a predictable state. This is preferable
to wait(), for being closer to real user interaction.
- wait() can trigger redraws and consequently generate more indeterminism.
Try removing wait().

By historical accident, Nvim defaults to background=light. So on a dark
background, `:colorscheme default` looks completely wrong.
The "smart" logic that Vim uses is confusing for anyone who uses Vim on
multiple platforms, so rather than mimic that, pick the (hopefully) most
common default.
- Since Neovim is dark-powered, we assume most users have dark backgrounds.
- Most of the GUIs tend to have a dark background by default.
ref #6289
According to POSIX[0], only octal escapes are supported by the printf
command. GNU coreutils' printf and some shells' builtin printf versions
which support hex escapes, but dash and non-GNU printf do not.

- Vim "unix default" of 'noshowcmd' is serving few users. And it's
inconsistent.
- 'ruler' and 'belloff=all' improve the out-of-the-box experience.
- Continue to use 'noshowcmd' and 'noruler' by default in the functional
tests to keep them fast.
TODO: Add a "disable slow stuff" command or mapping to address the
use-case of a very slow terminal connection.
This ameliorates use-cases like:
:!cat foo.txt
:make
where the user is interested in the last few lines of output.
Try these shell-based ex-commands before/after this commit:
:grep -r '' *
:make
:!yes
:!grep -r '' *
:!git grep ''
:!cat foo
:!echo foo
:!while true; do date; done
:!for i in `seq 1 20000`; do echo XXXXXXXXXX $i; done
In all cases the last few lines of the command should always be shown,
regardless of where throttling was triggered.
Periodically skip :! spam. This is a "cheat" that works for all UIs and greatly
improves responsiveness when :! spams MB or GB of output:
:!yes
:!while true; do date; done
:!git grep ''
:grep -r '' *
After ~10KB of data is seen from a single :! invocation, output will be skipped
for ~1s and three dots "..." will pulse in the bottom-left. Thereafter the
behavior alternates at every:
* 10KB received
* ~1s throttled
This also avoids out-of-memory which could happen with large :! outputs.
Note: This commit does not change the behavior of execute(':!foo').
execute(':!foo') returns the string ':!foo^M', it captures *only* Vim
messages, *not* shell command output. Vim behaves the same way.
Use system('foo') for capturing shell command output.
Closes#1234
