svnperms.py: won't match something it should match!

[Alexis Huxley <ah...@gmx.net>]

I've got a repository laid out like this:

	foo/trunk/foo.c
	foo/tags/release-1.0/foo.c
	foo/tags/release-1.1/foo.c
	foo/branches/bug-coredump/foo.c
	bar/trunk/bar.c
	bar/tags/release-0.1/bar.c
	bar/branches/bug-crash-on-zero-val/bar.c

etc. I'm using a one line pre-commit hook calling:

	svnperms.py -r "$1" -t "$2" 

and using svnperms.py's conf file to enforce that 
only 'admins' can create top-level directories 
(alongside 'foo' and 'bar'). So I did:

	[myrepo groups]
	admins = alexis

	[myrepo]
	[^/]+/ = @admins(add,remove,update)

There are no other regexps specified. But this does
not allow 'alexis' to create the create directories:

	Adding         new-module
	svn: Commit failed (details follow):
	svn: 'pre-commit' hook failed with error output:
	error: you don't have enough permissions for this transaction:
	you can't add new-module/

By changing the regexp to .* I have verified that
the hook is being called, calling svnperms.py, that 
its conf file is being read, that the group is interpreted
correctly and that I am authenticated as a member of
the group, etc.

I cannot find any documentation for svnperms.py, but
have managed by experimentation and examining source
code to work out that:

	- directories automatically get /-suffixed before
	  comparison with the regex

	- all regexps are automatically surrounded by ^ and $

The regex does match the path as verified with:

	perl -e '"new-module/" =~ m@^[^/]+/$@ && print "match\n";'

svnperms.py is the one available now at
http://svn.collab.net/repos/svn/trunk/tools/hook-scripts/svnperms.py.

Any help/advice appreciated! Thanks!
