Sure, but it might take me a few days...

I'm not too familiar with the relatively new RevisionLog and
VersionedProperty classes, so I can't say I completely follow what
you've done. However, I have a couple of comments anyway.
In this new section of code:
try:
old_value = self.raw_get(log.begin-1)
except LaunchError:
# The specified URL might not exist before the
# range of the log. If so, we can safely assume
# that the property was empty at that time.
old_value = { }
Wouldn't it be better to check the situation of the non-existent URL
explicitly rather than relying on LaunchError? LaunchError might occur
for other reasons.
In this section of code (the one which my original patch addressed),
my patch was setting old_revs only for the first loop -- it looks like
here some extra work is being done because old_revs is initialized at
the beginning of the loop every time, which shouldn't be required
because of the last line in the loop:
for rev in merge_metadata.changed_revs():
old_revs = merge_metadata.get(rev-1).get(target_dir)
new_revs = merge_metadata.get(rev).get(target_dir)
if new_revs != old_revs:
reflected_revs.append("%s" % rev)
old_revs = new_revs
Cheers,
Raman
