bug: svn relocate doesn't update relative externals for individual directories

Hi,
I've run into an issue using svn relocate on a directory that has
relative svn:externals properties on it. It is similar to the issue
that was resolved in Issue 3597 but that only works correctly with a
completely checked out version of the repository. I would like to have
this functionality for checking out a single directory in the repository
and not have to check out everything.

My repository structure looks like this:

/
/common_files
/application1
/application2

** The common_files directory contains special files that can apply to
all applications.

** The application directories each have this svn:externals property on
them: ../common_files/common.file common.file

If I check out the entire repository from one URL and do an svn relocate
to another URL it correctly updates the URL for the external file but if
I only check out application1 from one URL and do an svn relocate to
another URL the external file still points to the first URL.

This problem only started creeping up because we've changed from using
the file protocol to access our repositories to using svnserve. We use
TortoiseSVN 1.6.12 which uses Subversion 1.6.15.

Could someone confirm that this is a bug and direct me to what I should
do next to get it resolved?

Thank you,
