always interpret VS16 as a wide character and assume the terminal does
likewise. This is behaviour seen in a number of newer terminals' Unicode
14 support but not in older terminals; it seems to be a little
contentious and is currently difficult to detect.
Probably in the long run tmux should pick a behaviour, look at a (new)
terminfo(5) capability to tell it what the terminal will do, and emulate
as required, but at this point I'm not sure that is worth it for
something where support is mixed, seems to be in flux, and that mostly
only matters for emojis.

that it is emulating them by setting a bright (or bold) flag; however,
when the colour is changed from a bright colour (say SGR 96) to a
non-bright (say SGR 36), the flag is not reset, so the new colour
remains as bright. SGR 39 (default colour) also does not reset, so you
end up with the bright default colour. Work around this by sending SGR 0
when switching away from a bright colour, and disable AX for TERM=linux.

correctly, it was intended to skip lines that are already being searched
as part of a previous wrapped line but in fact is skipping all lines
except the last in wrapped lines.
Also revert the search-wrapped-lines option (I didn't realize it was
intended to work around this).
