This is needed here, because am-opts no longer has the
committer-date-is-author-date passed through with the
parse_options() call in cmd_rebase(), which makes sense.

Hmph, are we sure that author-script is always available at this
point so that a call to read_author_date_or_die() is safe? There
are three callers to the run_git_commit() function and I am not sure
if codepaths that reach all of them prepared the input to the
read_author_script() helper.

In the same function, we seem to be grabbing the author ident by
calling get_author(message), where the message is an in-core copy of
a commit object, which suggests me that we may not necessarily be
working with the on-disk information read_author_date_or_die() is
prepared to deal with. Are we sure we have the needed information
on disk so that read_author_date_or_die() will read the correct
information from the disk?

These two are propagating the option across rebase invocations, and
they should be correct (as correct as how correctly other options
are propagated ;-)).

This codepath does have read_env_script() which reads from the
author script an earlier call to write_author_script() would have
left on disk (at least when do_merge() is called with 'commit'
argument, anyway), so we should be able to read from it (or the
existing code is already buggy---and this patch just makes it
slightly worse by depending on a wrong assumption even more). OK.
