That was output to stdout made from the update hook in my case.
I do not know your setup, but if you make sure your update hook
does not spit out anything to its stdout (diag can go to stderr),
you should be able to work it around.

Funny thing is, at least in recent enough git, I think we set up
redirection to force output from hook scripts to stderr, but I
do not remember when it happened.  Let's see...

	...goes and looks...

That was supposed to have been fixed with commit cd83c74c (Dec
30, 2006), but this indicates the fix is not working at all when
your login shell is tcsh.

Hmmmmmm.....
