Yeah, you're right. I didn't even remember that commit at all. On the
off chance that the abbreviation code was different in that earlier
version, I also checked rebasing 01319837 with an older version, but it
does work fine.

So yeah, the most plausible theory to me so far is unluckiness combined
with pre-1.8.4.2. That should be easy to disprove if Henning tells us
his git version.
