[PATCHv2 0/4] pre-commit hook for merges

[Michael J Gruber <git@drmicha.warpmail.net>]

In this second iteration I implement Junio's suggestion: 'git merge' invokes
the pre-commit hook when merge.usePreCommitHook is set to true.

1/4 documents that 'git merge' invokes the prepare-commit-msg hook
unconditionally already.

2-4 are v2 of the previous 1-3.

This leaves aside the issue of commit-msg and post-commit hooks. If we can live
with a bit of incompatibility I would rename the config to merge.useCommitHooks
and call all of them based on that.  This would change the way prepare-commit-msg is
treated now.

We could also introduce 4 config variables, 3 defaulting to false, 1 to true,
of course...

[I had messed up my alias file when adding mhagger, and it seems that tripped up
vger; resending, sorry.]

Michael J Gruber (4):
  merge: document prepare-commit-msg hook usage
  git-merge: Honor pre-commit hook based on config
  merge: --no-verify to bypass pre-commit hook
  t7503: add tests for pre-commit hook (merge)
