git-gui: use +/- instead of ]/[ to show more/less context in diff

chunga · spearce · commit 729ffa50f75a · 2008-04-05T00:03:19.000-04:00
On some systems, brackets cannot be used as event details
(they don't have a keysym), so use +/- instead (both on
keyboard and keypad) and add ctrl-= as a synonym of ctrl-+
for convenience.

[sp: Had to change accelerator to show only "$M1T-="; the
     original version included "$M1T-+ $M1T-=" but this is
	 not drawn at all on Mac OS X.]
