When working with a subdirectory in a repository, how to find the revision when that specific directory has been added to the repository? By using "svn info http://.." I can find out when it was modified for the last time ("Last Changed Rev"), but I also need to find out the revision number of the commit when that directory (or file) was added for the first time (it's "first" revision).
I have been searching for that at the "SVN book", googling, but, obviously, I got no results.
