How to delete directory with at symbol in the name

[Russell E Glaue]

If you accidentally put the at symbol in a directory name like this:

svn copy http://svn.domain.com/repos/trunk/my...@49 http://svn.domain.com/repos
/trunk/my...@head -m "bring back rev 49 from the dead"

You end up with the following path in HEAD: '/trunk/my...@head/'
Where '@HEAD' is part of the actual directory name.

How would you delete this 'my...@head' directory?

Using svn delete myd...@head or mydir@HEAD do not work.
Any help?
