One improvement, if you're looking for a fairly recent change is to
bound the blame command with a revision range (I find a date up to
HEAD as easiest).  You'll miss annotations on lines which were last
touched prior to the selected range, but it can definitely speed
things up.

On a file like News, even if you're generous (say take the last year)
it would probably be noticeably faster than letting svn go back to
revision 1.
