Why does "merge --continue" expect no arguments?

There are several git commands that take a "--continue"
option...`merge`, `rebase`, `cherry-pick`, etc. From looking through
the source though, only `merge --continue` seems to expect no other
arguments. Suppose that you have just resolved some merge conflicts,
and then want to run `git merge --continue --no-edit` to accept the
default merge commit message. Having to open/close the configured text
editor still is mildly annoying. I'm interested in submitting a patch
to "fix" this `merge` behavior, but I wanted to check if this was
really the intended behavior first, and if so why.

Thanks,
