Using the to-do list command `squash` the user can specify two or
more commits and git-rebase creates one commit that introduces all
their changes combined. The authorship for the created commit is
taken from the first commit specified and the user can edit the log
message. There is a variant of `squash` available named `fixup` which
also takes the first log message without asking for user input.
While it is reasonable to not verify replayed changes twice or
rejecting some other author's changes in her name, it is insufficient
to not verify the user input used as log message in the case of
`squash`. Specify the git-commit option `--no-pre-commit` instead of
`--no-verify` when committing the squash result, but not before, to
let the commit-msg hook verify the final squash message. For the same
reasons the pre-commit hook is disabled in all replay modes, the
commit-msg hook is disabled in `fixup` mode.
Add tests. In addition to the existing test checking that the
pre-commit hook is disabled when simply picking a commit, provide a
test checking that the commit-msg hook is disabled as well.
