Phillip Wood 9d6b9df128 rebase -i: fix rewording with --committer-date-is-author-date
baf8ec8d3a (rebase -r: don't write .git/MERGE_MSG when
fast-forwarding, 2021-08-20) stopped reading the author script in
run_git_commit() when rewording a commit. This is normally safe
because "git commit --amend" preserves the authorship. However if the
user passes "--committer-date-is-author-date" then we need to read the
author date from the author script when rewording. Fix this regression
by tightening the check for when it is safe to skip reading the author
script.

Johannes Schindelin d1c02d93b3 t34*: adjust the references to the default branch name "main"
Carefully excluding t3404, which sees independent development elsewhere
at the time of writing, we use `main` as the default branch name in
t34*. This trick was performed via

	$ (cd t &&
	   sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \
		-e 's/Master/Main/g' -- t34*.sh &&
	   git checkout HEAD -- t34\*)

This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main`
for those tests.

Jeff King 5f35edd9d7 rebase: fix broken email with --committer-date-is-author-date
Commit 7573cec52c (rebase -i: support --committer-date-is-author-date,
2020-08-17) copied the committer ident-parsing code from builtin/am.c.
And in doing so, it copied a bug in which we always set the email to an
empty string. We fixed the version in git-am in the previous commit;
this commit fixes the copied code.

Jeff King 16b0bb99ea am: fix broken email with --committer-date-is-author-date
Commit e8cbe2118a (am: stop exporting GIT_COMMITTER_DATE, 2020-08-17)
rewrote the code for setting the committer date to use fmt_ident(),
rather than setting an environment variable and letting commit_tree()
handle it. But it introduced two bugs:

  - we use the author email string instead of the committer email

  - when parsing the committer ident, we used the wrong variable to
    compute the length of the email, resulting in it always being a
    zero-length string

This commit fixes both, which causes our test of this option via the
rebase "apply" backend to now succeed.

Jeff King 56706dba33 t3436: check --committer-date-is-author-date result more carefully
After running "rebase --committer-date-is-author-date", we confirm that
the committer date is the same as the author date. However, we don't
look at any other parts of the committer ident line to make sure we
didn't screw them up. And indeed, there are a few bugs here. Depending
on the rebase backend in use, we may accidentally use the author email
instead of the committer's, or even an empty string.

Let's teach our test_ctime_is_atime helper to check the committer name
and email, which reveals several failing tests.

Rohit Ashiwal 27126692ba rebase: add --reset-author-date
The previous commit introduced --ignore-date flag to rebase -i, but the
name is rather vague as it does not say whether the author date or the
committer date is ignored. Add an alias to convey the precise purpose.

Phillip Wood a3894aad67 rebase -i: support --ignore-date
Rebase is implemented with two different backends - 'apply' and
'merge' each of which support a different set of options. In
particular the apply backend supports a number of options implemented
by 'git am' that are not implemented in the merge backend. This means
that the available options are different depending on which backend is
used which is confusing. This patch adds support for the --ignore-date
option to the merge backend. This option uses the current time as the
author date rather than reusing the original author date when
rewriting commits. We take care to handle the combination of
--ignore-date and --committer-date-is-author-date in the same way as
the apply backend.

Rohit Ashiwal ef484add9f rebase -i: add --ignore-whitespace flag
Rebase is implemented with two different backends - 'apply' and
'merge' each of which support a different set of options. In
particular the apply backend supports a number of options implemented
by 'git am' that are not implemented in the merge backend. This means
that the available options are different depending on which backend is
used which is confusing. This patch adds support for the
--ignore-whitespace option to the merge backend. This option treats
lines with only whitespace changes as unchanged and is implemented in
the merge backend by translating it to -Xignore-space-change.
