Don't forget to use the "reply to all" feature of your email program
when replying so that your reply also goes to the mailing list and
not just to me.
I agree the wording in the manual could be clearer. That seems to be
the gist of this message:
http://svn.haxx.se/dev/archive-2006-03/1256.shtml
But before replying to your initial mail I did try it out and was
unable to get my output displayed by the client unless I exited the
hook with a nonzero code. That seems to be the intended behavior.
There has been other discussion on the lists about this topic, and I
believe the idea was that there is no communication channel between
the client and server over which a message could be transmitted in
the case of success, and adding it would be non-trivial. (There have
also been requests to make hooks interactive, which is even less
trivial.) It's also been called into question what the purpose would
be of printing output in the case of success. If you must inform the
user of something after every commit, you could do so in an email
sent from the hook. Since you know the username you can presumably
construct or look up their email address.
