[PATCH v5.1 0/8] redo ssh-signing-key-lifetime topic

So, here is a quick attempt to move the fixes to the existing tests to the front as a preliminary clean-up as [1/8], and stop step [7/8] (used to be [6/8]) from copying the mistake we already cleaned in [1/8] from the beginning.

No other changes intended, although I think I fixed a typo in the proposed log message in [1/8] (the early half of the old [8/8]).

Fabian Stelzer (8):
  t/fmt-merge-msg: make gpg/ssh tests more specific
  ssh signing: use sigc struct to pass payload
  ssh signing: add key lifetime test prereqs
  ssh signing: make verify-commit consider key lifetime
  ssh signing: make git log verify key lifetime
  ssh signing: make verify-tag consider key lifetime
  ssh signing: make fmt-merge-msg consider key lifetime
  ssh signing: verify ssh-keygen in test prereq
