subrepo: use [0-9] instead of [\d] in svn subrepo regex
The \d was used in a normal (not raw) string and was only passed
through to re.search because Python does not define that escape
character itself. Using 0-9 makes it clearer what is happening.
Basic install:
$ make # see install targets
$ make install # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg # see help
