When writing large amounts of data to the tty it is common to first hide
the cursor to avoid a flickering effect. This has been done in Nvim for
a long time and was implemented in the function that actually flushed
the TUI buffer out to the TTY.
However, when using synchronized updates with the 'termsync' option this
is no longer necessary, as the terminal emulator will buffer all of the
updates and display them atomically. Thus there is no need to toggle the
cursor visibility when flushing the buffer when synchronized updates are
used. In fact, doing so can actually reintroduce cursor flickering in
certain scenarios because the visibility state is itself being
synchronized by the terminal.
In addition, the management of the cursor visibility should not happen
when the TUI _buffer_ is flushed, but rather when the TUI itself is
flushed. This is a subtle but meaningful distinction: the former
literally writes bytes to the TTY while the latter flushes the TUI's
grid into its buffer. There is no need to hide the cursor every time we
write bytes to the TTY, only at the beginning of a full TUI "flush"
event.
This fixes an error that can occur in certain pathological cases when
the autocommand fires at just the right time such that it attempts to
close the timer after the timer has already exited, but before the
scheduled callback has fired.
We now let the timer continue to run even when the autocommand deletes
itself to avoid having to repeat the cleanup code multiple times. There
is no harm in letting the timer execute if the autocommand does not
exist, as the pcall will catch the error.
Problem: wast filetype should be replaced by wat filetype
Solution: start using the official wat filetype name
runtime: rename `wast` filetype to `wat` (Wasm text format)
The problem is the name of the current filetype wast. When the plugin
was initially created, the file extension for Wasm text format was not
fixed and .wast was more popular.
However, recently .wat became the official file extension for
WebAssembly text (WAT) format and .wast is now a file extension for the
unofficial WAST format, which is a superset of .wat for the convenience
to describe the Wasm specification conformance tests.
https://webassembly.js.org/docs/contrib-wat-vs-wast.html
However for now, let's keep using the `wat` filetype even for the .wast
extension, so that we at least do not lose the filetype settings and
syntax highlighting. This can be adjusted later, if it turns out to have
a separate need for.

The 'termsync' option enables a mode (provided the underlying terminal
supports it) where all screen updates during a redraw cycle are buffered
and drawn together when the redraw is complete. This eliminates tearing
or flickering in cases where Nvim redraws slower than the terminal
redraws the screen.
Problem:
Platform-specific UI providers should live in `vim.ui.*`. #24164
Solution:
- Move `vim.clipboard.osc52` module to `vim.ui.clipboard.osc52`.
- TODO: move all of `clipboard.vim` to `vim.ui.clipboard`.
ref #25872
Problem:
'nofsync' may lose data if the system has a hard shutdown. #9888
Solution:
Change default to 'fsync'. This may be revisited in the future when
'nofsync' can be made safer.
If Nvim is in the process of exiting then we do not want to allocate any
new refs onto the event loop, because they will not be freed and will
result in a memory leak.
libtermkey does not interpret OSC sequences that end with a BEL (0x07)
instead of an ST (0x1b 0x5c) terminator. This causes these tests to fail
since the OSC response is now parsed via libtermkey. Change the tests to
use the ST terminator to appease libtermkey.
Problem:
Numerous Vim 8.1 patches are listed by `vim-patch.sh -l`.
Solution:
Mark the following patches as N/A:
