Subject: [PATCH] Fix undesired line wrap in :Git output

If Vim is 100 columns wide, and we echo a string exactly 100 characters
long, Vim will insert a line break that a terminal wouldn't.  This is
particularly noticeable with progress bars that Git erases with a screen
width's worth of whitespace.  Work around this by decreasing the number
of columns by 1.
