I just pulled this and built a darcs with it compiled in. In my first
test, I found it was about 10x faster than 1.0.2 for this kind of diff:
darcs diff file.txt
In practical terms, this mens the time dropped from about 5 seconds to
.5 seconds, a very noticeable difference.
Thanks!
Now I think I'll have to update some documentation in a few places that
referred to 'darcs diff' being slow. :)
This may also nudge me to start a performance test suite for darcs...
