[PATCH v2 3/4] merge: --no-verify to bypass pre-merge hook

[Josh Steadmon <steadmon@google.com>]

From: Michael J Gruber <git@grubix.eu>

Analogous to commit, introduce a '--no-verify' option which bypasses the
pre-merge hook. The shorthand '-n' is taken by the (non-existing)
'--no-stat' already.

[js: cleaned up trailing whitespace, moved some documentation changes
 from this commit to 2/4.]
