98610fcd37 Do not interpret CSI ? u as DECRC
The kitty keyboard protocol docs recommend CSI ? u to query support for
that protocol, see https://sw.kovidgoyal.net/kitty/keyboard-protocol/

For better or worse, fish shell uses this query to work around bugs
in other terminals triggered by requesting that protocol via CSI = 5 u.

Unfortunately, st interprets CSI ? u as DECRC (restore cursor
position). reproduce with 'printf "\x1b[?u"; cat'.

fish could work around this by switching to the alternate screen
before running this query; but that might cause tearing on terminals
that don't support Synchronized Output. I'm not sure.

In the meantime, let's correct our parser.

This adds a redundant else-after-return, for consistency with the
surrounding code.

a0274bc20e fix BadMatch error when embedding on some windows
When embedded, st fails with BadMatch error if the embedder's window has
non-default colormap/depth/visual.  This commit fixes that by creating
st's window inside root and then reparent it into embedder.

The reference window for dc.gc is also changed to match root's visuals.

A similar commit had been made for dmenu[1].
See this issue[2] on github for context.

5dbcca4926 support colons in SGR character attributes
Patch by Mikhail Kot <to@myrrc.dev>
With some modifications to behave more like xterm (see note below).

Example:

	printf '\033[48;2;255:0:0mtest\n'

https://invisible-island.net/xterm/ctlseqs/ctlseqs.html

Some notes:

"CSI Pm m  Character Attributes (SGR).
[...]
o   xterm allows either colons (standard) or semicolons
(legacy) to separate the subparameters (but after the
first colon, colons must be used).

497a756382 Reset title when an empty title string is given
With this patch, st will reset its window title when an empty string is
given as the terminal title. For example:
	printf "\033]0;\007"

Some applications, like termdown, expect this functionality. xterm
implements it, but it seems that most other terminal emulators don't.
In any case, I don't see why there should ever be a case where the st
window doesn't have a title property.

8c68ec5241 Revert "Fix cursor move with wide glyphs"
This reverts commit 7473a8d1a5.

This patch needs some more work. It caused regressions with programs that use
GNU readline, etc.

Original test-case example from Tim Culverhouse <tim@timculverhouse.com>:

	printf " 😀" && sleep 2 && printf "\e[D" && sleep 2 && printf "\e[D" && sleep 2

After the patch it caused regressions, example test-case:

	printf "A字\bB\n"
