From: Michael J Gruber <g...@drmicha.warpmail.net>
Analogous to commit, introduce a '--no-verify' option which bypasses the
pre-merge-commit hook. The shorthand '-n' is taken by '--no-stat'
already.
[js: * reworded commit message to reflect current state of --no-stat flag
and new hook name
* fixed flag documentation to reflect new hook name
* cleaned up trailing whitespace
* squashed test changes from the original series' patch 4/4
* modified tests to follow pattern from this series' patch 1/4
* added a test case for --no-verify with non-executable hook
* when testing that the merge hook did not run, make sure we
actually have a merge to perform (by resetting the "side" branch
to its original state).
