[PATCH] Enhancement to svnperms.py to read sections via regex

Hi,

The svnperms.py script reads the svnperms.conf file, which needs the
section rules for all the repos uniquely. This was quite tough when we
have n number if repos. I wished that svnperms.py reads regex matches
and applies the configuration rules and came up with this patch.
Mid-way of my coding work, I came to know that -s switch would let us
specify the section name explicitly, but not the regex thing.
I modified the code to search for a matching section via regex, which
might be really helpfull for certain cases.
I have attached the log file and the patch file with this mail for
review.

Thanks and regards,

[[[
Make svnperms.py to accept repo section names via regex rather than absolute.
* tools/hook-scripts/svnperms.py
  (check_perms): If absolute section is not found, try to find it by
   matching as a regex.

* tools/hook-scripts/svnperms.conf.example
  (): Add some default section example.
