svn:merginfo propogating unnecessarily?

At my company we are using SVN 1.6.4 (server) and a variety of clients
(SmartSVN, Tortoise, command-line).

At first we wanted to keep things simple and just always do merges at the
root level (e.g., in c:\branch run "svn merge -c 12345
https://host/svn/trunk").

Unfortunately, merging was taking a considerable amount of time (up to
several minutes), so we started doing merges at lower subdirectory levels
(e.g., in c:\branch\subdir1\subdir2 running "svn merge -c 12345
https://host/svn/trunk/subdir1/subdir2).

Unfortunately now the svn:mergeinfo properties have started showing up all
over the place. That's not a problem in itself, but when we do a merge it
updates every subdir / subfile that has a svn:mergeinfo property.
Personally I think SVN ought to update only subdirs that are related to the
change (e.g., ancestors of changed files). Not only would that keep the
svn:megeinfo from propagating all over, but it would speed up merges.

Is this something that is on the horizon to be fixed, or am I missing
something? I'm not subscribed to the list, so please CC me on any response.

Thanks,
Phillip
