Hi,

I can't scroll, click, select,... with the mouse any more if I'm running
vim inside screen using xterm or urxvt (I have "set mouse=a" in my
.vimrc ofc). If I run vim directly in xterm/urxvt without screen, mouse
works.

If I revert the following 2 patches (I didn't try reverting only one
because the 2nd seems to be a fixup) it works fine in urxvt, xterm,
xterm/urxvt + screen.

I'm currently running gvim 7.3 patchlevel 353 on Arch Linux.
