_subversion

[Clint Adams <clint@xxxxxxx>]

This is some rudimentary completion for svn and svnadmin.
Oliver already tweaked a line.

Known issues include that it doesn't handle multiple usages, f.ex:

====
usage: 1. export [-r REV] URL [PATH]
       2. export PATH1 PATH2
====

Also, it doesn't know how to delve into the actual repositories.
