That's a good point...

That sounds reasonable. Do you know how stable the "entries" file is
within the .svn directories with respect to versions? Ie. Does it exist
in old versions as well as in recent ones? (My knowledge of subversion's
directory contents are rather limited.)

The other backends should not suffer from this problems. All others that
look for a directory to detect a VCS already look for a file in addition
to the directory. I don't remember why we didn't do this for svn
earlier, too. Probably because nobody complained. :)
