Can git-svn correctly populate svn:mergeinfo properties?

I am evaluating git-svn and trying to determine how well it will play with a particular svn repository. I am mostly concerned with getting git-svn to perform merges in such a way that the svn:mergeinfo property is correctly set in the subversion repo. Is this possible?

Here is what I have done so far:

# Checkout the SVN repo.
$ git svn clone svn://server/project1 -T trunk -b branches -t tags

# Make sure we are working on trunk.
$ git reset --hard remotes/trunk

# Modify the working copy.
$ vim file.txt

# Commit locally to the git repo.
$ git commit -a

# Push the commits back to the SVN server.
$ git svn dcommit
Committing to svn://server/project1/trunk ...
    M   file.txt
Committed r178
    M   file.txt
r178 = b6e4a3a0c28e7b9aa71d8058d96dcfe7c8a2b349 (trunk)

Now how would I go about merging that particular commit into one of the subversion branches? Again, it is very important to me that git properly set the svn:mergeinfo property when committing the change.
