Is there a way to exclude the diff of certain files?

Hi there,

I have a test SQL dump which is quite large.  When running through the list of changes prior to commits, I usually diff them.  The problem is that when it gets to the SQL file it hangs for a bit of time while it's churning out the deltas.  Is there a way to exclude diffs on certain types of files, trap long deltas with a warning to the user, or exclude diffs where the delta > 75% of the file?
