[PATCH] patch solving <Location /> problem

(Resent to follow the HACKING guidelines.)

Log message:

--
* repos.c
  (dav_svn_get_resource): do not remove the trailing slash for the root, /.
--
Problem description:
The problem was, you couldn't host SVN repository at the top level,
at http://svn.host.tld/, since the <Location /> was parsed incorrectly
in mod_dav_svn -- the trailing slash was misinterpreted as missing for
root, another / added, and / was redirected to //, which couldn't exist.
The problem existed for the / location only.
Greg Stein suggested the fix, which follows as a patch, 
tested and working.  :-)
Cheers,
Alexy
