GUB and unfortunate travel timing

[Graham Percival]

Hey guys,

It seems like we've got solutions for 1933, 1943, and 1948.  2160
was fixed as a side note to the website pdf patch by Alberto.
Dealing with git branches (issue 2100) is the only one that isn't
either finished or really close to being finished, but I expect
that patch just needs something like 1 hour of
writing+research+reviews.

Unfortunately, I'm leaving for Glasgow in 3 hours, so any official
releases with the fixed 1933/1943/1948 will have to wait until
Friday afternoon.  If you're really anxious to test stuff, by all
means build binaries with those fixes, upload them to a private
server, and ask users to test them.

Best-case scenario: we could have the third release candidate on
Friday 6 Jan, with the official 2.16 release on Friday 13 Jan.
That's an extremely ambitious schedule, so it's more realistic to
think of 2.16 before the end of January -- but given the sudden
interest [1] in having a stable release, I think that's certainly
doable!

[1] recall that I define "interest" as "writing or discussing
patches", not "writing emails to say how much you want other
people to do some kind of work".

Cheers,
- Graham
