Firstly, this allows a staged rollout in load-balancing situations
wherein we turn on "allow" for all servers, then "advertise", so that we
don't end up with a client that sees the advertisement but then sends
the follow-up request to a server that has not received the latest
configuration yet.
Secondly, I wonder if some people purposely set HEAD to an unborn branch
just so that the repository would be presented as not having a HEAD.
Now, the name of the unborn branch would be revealed. I don't know if
that's a problem, though - but if it is, at least this configuration
variable is a way to solve that.
I'll include this in the documentation in a next version of this patch
set.
