Yes, I am running git 1.7.2.5 on Debian Squeeze, but I will be upgrading
in the next month, before the next major release notes are due, so I
would avoid the problem that way. :-)

Well, my idea would be to change this git_changelog line:

Branch: master [01051a987] 2015-07-09 11:38:34 +0300

to output something in the new 'trunc' format, so we have it right next
to the release note text and the release notes easily get that comment.

If we _don't_ do that, how do you easily get those lines into the
release notes? I can't imagine how hard it was for Andres to add that
text to the 9.5 release notes:
