f8b863598c ("builtin/merge: honor commit-msg hook for merges", 2017-09-07)
introduced the no-verify flag to merge for bypassing the commit-msg
hook, though in a different way from the implementation in commit.c.

Change the implementation in merge.c to be the same as in commit.c so
that both do the same in the same way. This also changes the output of
"git merge --help" to be more clear that the hook return code is
respected by default.

[js: reworded commit message, and moved documentation changes from patch
 3/4 to this commit.]
