Merge shows conflicts on files that didn't change? (was Re: Question about merging)

I guess it's time for my ~yearly question about why SVN can never seem
to do this merge properly... Summary: I have a "releaseA" branch off of
trunk, then a "releaseA + custom stuff" branch off of "releaseA". I also
have a "releaseB" branch off of trunk. I want to merge "custom stuff"
into "releaseB" to create a "releaseB + custom stuff" branch, but SVN is
showing a ton of updates/conflicts, even though "custom stuff" only
touches a handful of files (as confirmed by a diff between "releaseA"
and "releaseA + custom stuff").

See the thread starting at
http://mail-archives.apache.org/mod_mbox/subversion-users/201009.mbox/%3C3852DC49-BC93-45AB-A22E-1F5391257C49%40azeotrope.org%3E
for more info.

I just tried this again with SVN 1.7.2 on the client and 1.6.15 on the
server, and it still doesn't work right.
