There are no termcap entries about the mouse handling. This is hard
coded in the Vim sources. Have a look at src/term.c, search for
mouse_col.
I thought there was a todo entry to support more columns for xterm, but
I can't find it now.
If you can make a patch, that would be welcome. Do try to make it work
for everybody. If it's a mode switch then that is very tricky, because
it has to be restored when Vim exits (and when it crashes...?).
Everything depends on the name of the terminal, but that often makes
users set $TERM to xterm even though it's not actually an xterm and then
later something causes a problem. Perhaps we need a separate option for
this. But hopefully automatic detection works.
