[PATCH 2/8] git-remote-testgit: exit gracefully after push

[Jeff King <peff@peff.net>]

The core of the helper script is a loop reading commands.
After most commands, we want to read more, until we get an
empty command that signals we're done. The "export" command
is different, though; all of the rest of the input goes to
fast-import, and there is nothing left for us to read.  This
caused us to print a warning that we got EOF, even though it
is expected in this case.

This was just a warning, so it didn't cause any tests to
fail, but the testgit helper is supposed to act as a
reference implementation. We should try to set a good
example.

This patch lets each command handler tell the main loop
whether it should expect more commands or not; the handler
exits gracefully if no more are expected.
