Whoops. I obviously did not actually run the test suite. I think when
writing the commit message, my brain said "we are not changing anything,
so no need to run the tests", forgetting that I did not run them the
first time when posting an untested "eh, how about this" patch.

Yeah, that works. We could also advance "p" in the DATE_STRFTIME
conditional, but I think your solution is less ugly.

Thanks for debugging my mess.
