Bug#649943: vim: scroll-by-mouse broken, ttymouse=xterm has to be set after each :! to reenable it again

[Konstantin Schukraft]

Package: vim
Version: 2:7.3.346-1+b1
Severity: normal

After the update from 7.3.333 to 7.3.346 vim started the odd behaviour
of not letting me scroll with my mouse after I ran :! commands. I have
to set ttymouse
again to xterm or xterm2, although it already has that value.
