[PATCH] git gui: visually wrap lines of commit message

Visually wrap lines in the commit message text box. That way we can avoid
a horizontal scroll bar (which was not available anyways).

Note: This does _not_ break lines in the actual commit message.

I also tried to get automatic line breaks but was unable to do so. I managed
to implement a callback function triggered by the <<Modified>> event, and I
also managed to query the end position of the insertion using the 'insert'
index. So with this information it would be possible to implement automatic
line breaks. Unfortunately, this is not enough for pasting. If there is more
than one new character, the start position of the insertion is unknown.

I then tried to track cursor movement, but no luck there either. Any ideas
are welcome. For now I'll simply have to "git commit --amend<CR>gqG:x<CR>"
each time I use git gui.
