someone reported an error on "my $_" (presumably old perl) but I now
realise the whole map is useless; both the lists concerned have already
been chomped.
...otherwise 'gitolite help' was getting too confusing, mixing up stuff
that users should not be running directly (even on the server)
----
implementation notes:
those who are worried about the '../triggers/' in various parts of the
code here, remember you can only do that from a command line on the
server. Remote users can only use commands that have been explicitly
listed in the COMMANDS hash in the rc file. This means they can't even
access other commands in the same directory as, say, the 'info' command,
so a '../' is definitely not going to work.
