I dislike the approach to use a separate command/option.
The nice thing about rebase-apply/original-commit is that
you can use it in /any/ git command, i. e. you can do "git
log $whatever..rebase-apply/original-commit".

What I would do instead is (besides documenting it :-)) to
provide an alias that is more in line with ORIG_HEAD,
FETCH_HEAD, etc.; i. e. something along the lines of (pseudo
code, will probably not work):

This (when working) would allow to use ORIG_COMMIT in place
of the mouthful rebase-apply/original-commit.
