File diffs in History view aren't sized to window size #50
Description
(Using 0.8.2beta)
For diffs that contain lines longer than can be displayed in the current window size, the file diff "blocks" extend wider than the window. This means that some information and the "Open in FileMerge" are hidden. If there are multiple files in the commit, then the diff "blocks" are sized differently, inconsistently.

Some other (older) versions of GitX had consistent sizes for the diff blocks, that matched the window width. For diffs with lines longer than the window widget, there was a scrollbar per file which allows viewing all of the diff contents. See http://i.imgur.com/ylpIa.png.
