[PATCH 0/7] fmt-merge-msg improvements

The first one might be considered a bug, although triggering it is
probably impossible. Not much of a price to pay for correctness
though.

The next two patches modernize and update the test a bit.

The next 3 patches try and reduce the code size by libifying(?)
fmt-merge-msg.

The final patch is just a "while I'm here" thing and might be
unnecessary if we decide to just remove the summary option.

Stephen Boyd (7):
  fmt-merge-msg: be quiet if nothing to merge
  t6200: modernize with test_tick
  t6200: test fmt-merge-msg more
  fmt-merge-msg: use pretty.c routines

  fmt-merge-msg: remove custom string_list implementation
  fmt-merge-msg: hide summary option
