Re: [PATCH] Allow update hooks to update refs on their own

Couldn't you do this with a status message? ("ok <refname> changed by 
hook" or something.)

Having just touched this code, I believe the answer is yes. receive-pack
has always sent just "ok <refname>\n", so we could start interpreting
anything after the <refname> bit freely...

More importantly, no send-pack choked on "ok <refname>" followed by a SP
(old ones just checked "ok" and nothing else, the current one NULs out
the SP and lets you use the rest as a message), so such a change to
receive-pack does not have to break older send-pack.
