Why?  If you can use -m msg, you should be able to use -F msgfile,
too, no?

Earlier I was thinking to let the `--fixup=amend:`  use the same options as of
current `--fixup=` . But yes I agree that there should be  -F option
also with `amend`
and `reword`.

Hmph, I was actually imagining the opposite---a context that does
not want to take -c/-C/-F would not want to take -m, either.

Why is -m so special, and a lot more importantly, what would a user
want to achieve by using "-m more-text" combined with this
"--fixup=reword:<commit>" or "--fixup=amend:<commit>" feature?
