present.

the previous suggestion seemed to be about the update hook, but it's
usually bad practice to setup notification hooks there, because if
they fail, the push fails.

parsing the git documentation to find exactly the incantation is not
exactly trivial either...

...but, alas, the server doesn't echo pings back to their sources.

...if we could see message traffic!

...immediate mode doesn't need it.

We can now send messages with -i but we don't ger clean termination
afterwards yet.
