How dramatic is the slowdown from your optimization if you run 'svn
log' on a file or directory which has few changes? From reading your
email, it seems like the slowdown will be very minor, but correct me
if I am wrong.

I do often run 'svn log --limit N' on an individual file or directory
to read about the last N changes to a particular file or directory. I
also find it handy to run "svn log -r1:HEAD --limit 1 --stop-on-copy"
to find the last revision in which a file was copied, or "svn log
-r1:HEAD --limit 1" to find the revision in which a file was created.
So far I haven't noticed any performance problems with these
operations, but if your change will have a dramatic effect on these
cases you might want to think about that.

Cheers,

David
