bug#19983: 24.4; exit-emacs regression in 24.4?


From: Sam Halliday
Subject: bug#19983: 24.4; exit-emacs regression in 24.4?
Date: Tue, 10 Mar 2015 23:17:39 +0000
User-agent: Notmuch/0.18.2 (http://notmuchmail.org) Emacs/24.4.1 (x86_64-pc-linux-gnu)

Hi all,

With logic added to my script to skip bad builds, I get the following,
which is really confusing because the emacs-24.3 tag is Sun Mar 10 2013
and this is well before that. It's part of some epic merge at some
point, and I think git just fails to calculate the correct steps between
the two tags. Any suggestions for a better bound to check within that
won't confuse git so much? What the earliest parent commit for the 24.4
branch before the 24.3 code freezes?
