In my opinion as a Subversion user, that sucks. I think I'll switch to Mercurial. Oh, no wait, the Subversion team agreed with me and changed the message.

If there *is* a work around, that is a security fail anyway. I hope, for your employers sake, you do not rely on security through obscurity.

I think it is a terrible message, because, if I see "403 forbidden" I call the network admin to find out why the web server is broken. If I see "You do not have permission to commit to $URL" I call the configuration manager to apply to join the list of committers.

Notwithstanding that the "403 forbidden" exposes a detail of implementation that you think could lead to a work around.

So where's the harm in telling them that in their native language rather than expecting them to understand HTTP response codes?

If a user is not meant to have permission to commit stuff to the repository, they certainly shouldn't have the necessary admin rights on the server to fix the problem.
