Issue #999 seems to have speeded up some comparisons, but I'm having some problems.

Background: I recently did an update on my branch to the latest version (X), then merged from the
trunk, creating version Y. If I show the branch's History, I see Y in bold. If I select Y and X in history and
compare them, I see the expected differences.

Problem 1: If I select my copy of the branch and do Compare With > Branch/Tag, and compare with
revision X, it still takes forever, comparing even the unchanged files. (The same thing happens if I
compare with a different branch.)

Problem 2: More importantly, it ends up reporting that there are no changes! Even if I select one of the
files that changed in the merge, and do the same comparison, it says there are no changes. I'm not
sure if this is a problem with the diff algorithm, or a caching problem (as in issue #1031). But it doesn't
seem to matter which revision I enter in the Branch/Tag dialog; it always says there are no changes.
The only way I can get a valid comparison is if I do Compare With > Revision. This one could be pretty
dangerous.
