I see your point.
However how often do you really want to create a tag called list?
As of now it's easy:
	git tag list
and for listing all tags you'd need to type:
	git tag --list
and if you want to create a tag called --list, I'd assume you'd go
	git tag -- --list
	# However:
	fatal: '--list' is not a valid tag name.

So even as of now certain tag names cannot be done easily.
Also you have to type two more dashes for an action you'd probably want
to perform more often (as opposed to creating a tag 'list')

In my (ideal) world we'd rather have this behavior:
 	git tag list
	# behaves the same as
	git tag

Now creating a tag called 'list' is not as easy, because 'list' is a
primary operating mode name, so we need to tell git we're actually
meaning the name as opposed to the operating mode:
	git tag create -- list
	# or even
	git tag create -- --list

Anyways despite my arguing, it seems you rather want to rather have the
leading double dashes everywhere for the operating modes?
So the plan is to not touch the parsing, but to adjust notes and stash ?

Thanks,
Stefan
