[PATCH v2 0/3] fixing some parse_commit() timestamp corner cases

Here's a v2 of my series. The behavior should be identical, but I've incorporated some comment and small code tweaks based on feedback from the first round.

I also added a fourth patch which adds a new comment explaining some of the cases that were alluded to in the earlier round's patch 3.

  [1/4]: t4212: avoid putting git on left-hand side of pipe
  [2/4]: parse_commit(): parse timestamp from end of line
  [3/4]: parse_commit(): handle broken whitespace-only timestamp
  [4/4]: parse_commit(): describe more date-parsing failure modes
