Solution: Request the "XM" entry and use it to set 'ttymouse' if possible.

set to a name that starts with "xterm", "mlterm", "screen", "tmux",
"st" (full match only), "st-" or "stterm", and 'ttymouse' is not set
already.
+ If the terminfo/termcap entry "XM" exists and the first number is
+ "1006" then 'ttymouse' will be set to "sgr". This works for many
+ modern terminals.
Additionally, if vim is compiled with the |+termresponse| feature and
|t_RV| is set to the escape sequence to request the xterm version
number, more intelligent detection is done.
