What is format-spec function in current git-blame.el? Neither my GNU
Emacs 22.2.1 nor Google knows anything about it.

It's part of Emacs since more than 9 years, imported from Gnus.

Thanks, I now see it in Gnus on my own computer, in
lisp/gnus/format-spec.el.gz.

GNU Emacs 22.2.1 (i486-pc-linux-gnu, GTK+ Version 2.12.11) of 2008-11-10
on raven, modified by Debian 

However, isn't it a bad idea to require Gnus(!) for git-blame to run? Gnus
is not installed on our server where I've encountered the problem. Was
format-spec actually moved to core emacs recently?
