gl-shell-setup has a "run as hosting user" piece that basically
automates the adding of the user's (new) key to the admin repo.
This is now gone. (It's not that hard to automate yourself if you want
to do it anyway, using gl-admin-push).
I did this because I needed to allow someone in through a gateway, and
realised that that has the exact same needs. So the whole scheme has
been changed to treat the proxy and the gitolite host as being two
different servers.
At that point it became cumbersome to do the second bit, and I left it
out.
Other changes:
- you can define exceptions for the default shell in gl-shell
- the doc has been simplified.
