I thought the scrollbar took up too much vertical space, so I did
not want to put in a horizontal scrollbar on a box that never should
require horizontal scrolling.  As Johannes points out...

That's a bug, and I now understand why you have a problem.  That box
should not be resizing itself.  Its supposed to be using a fixed
width font, and have a fixed number of columns, so you can format
a message including drawing ASCII art to explain yourself clearly
as you write a change.

I'll consider a patch that fixes the box so it doesn't resize under
8.5, but I won't apply one that applies virtual line wrapping as
then we lose the what-you-see-is-what-you-get property of the editor,
and that is a very important property for git-gui users.
