Apologies if this has already been raised or PEBCAK, but I've noticed
a bug where git log with certain date ranges breaks things. It appears
to be any --since date with a --until date in the future between
2014-12-01 and 2014-12-09. Dates from 2014-12-10 appear to work, and
so does the date 2015-12-01.

Ugh. Approxidate strikes again:

  for i in 2014-11-01 2013-12-01 2014-12-01; do
    ./test-date approxidate $i
  done

produces:

  2014-11-01 -> 2014-11-01 09:35:19 +0000
  2013-12-01 -> 2013-12-01 09:35:19 +0000
  2014-12-01 -> 2014-01-12 09:35:19 +0000

The first two are right, but the fourth one is not.  It's probably
something simple and stupid.

Less simple and stupid than I thought, but I think I have a fix. It is
not about December specifically, but about the date being in the future.
The first patch is a cleanup to help us more accurately test the bug;
the interesting bits are in the second one.

  [1/2]: pass TIME_DATE_NOW to approxidate future-check
  [2/2]: approxidate: allow ISO-like dates far in the future
