Yes, the difference between the ``screen`` and ``tmux`` termcap
entries is how they deal with italics and reverse-mode video.
That's the motivation for setting ``TERM=tmux``, as GNU screen
doesn't support italics and the terminfo for ``TERM=screen`` is
incorrect for use with tmux:
$ infocmp screen tmux
comparing screen to tmux.
comparing booleans.
comparing numbers.
ncv: NULL, NULL.
comparing strings.
ritm: NULL, '\E[23m'.
rmso: '\E[23m', '\E[27m'.
sitm: NULL, '\E[3m'.
smso: '\E[3m', '\E[7m'.
Most Vim functionality works correctly with ``TERM=tmux``, but
the mouse is detected incorrectly. It works for ``TERM=screen``
because of the special-case checks for ``screen`` (among others)
in Vim's ``use_xterm_like_mouse()`` function.
At present it appears that hard-coding knowledge of certain
terminals into Vim's source is the solution for determining the
correct mouse protocol, which is why I proposed adding support
for tmux in the above function. Is there a different way Vim
should be detecting the mouse protocol?
