Whenever the diff pane scrolls, highlight the corresponding file in the
file list on the right. For a large commit with many files and long
per-file diffs, this makes it easier to keep track of what you're looking
at.
This allows simplifying the prevfile and nextfile functions, because
all they have to do is scroll the diff pane.

The only change from v1 is the addition of the "$difffilestart eq {}"
condition, this should fix the flickering problem reported by Peter.
I didn't do anything about the search problem yet, will look into this
next. (Personally though, I think this is acceptable the way it is.)
