Excellent work, Dan! I'm especially impressed with your clearly
spelled out use cases. Feel free to commit.

If further feedback from the svnmerge list determines we want to make
tweaks to the names of the command-line options, we can make them as
needed.

( svnmerge developers, see http://svn.haxx.se/dev/archive-2006-03/1097.shtml
for Dan's original post, which hasn't shown up on the svnmerge list yet. )

This happens to me all the time! When I merge from trunk to 1.3.x, I
often run into conflicts, so I create a temporary merge branch. If I
tried to merge from the temporary merge branch to 1.3.x, the merge
metadata would be lost because svnmerge.py does not track indirect
metadata. To correct this metadata, I'd use svnmerge.py merge
--memory.

As a side note, I'm hoping to extend svnmerge.py to track metadata
across merge branches, but this is quite tricky to implement
correctly.

Great! This will be a very useful feature. I'm looking forward to your patch.

Cheers,

David
