'--all' was introduced for a long time, meanwhile, git supports to
customize the storage location under "refs/". when a new git user see
the usage like, 'git push origin --all', we might feel like we're
pushing _all_ the refs instead of just branches without looking at the
documents until we found the related description of it or '--mirror'.

"--all" sounds like it will include all things: branches, tags, but it only
includes branches under ref/heads/, which does cause a little confusion
for users.

"under refs/heads", right （^ヮ^）? But The overall is nice to
me, I'm sure I will use some to revise.

Maybe OPT_ALIAS() will be better?

I think it's suitable for this if there is no misunderstanding for
'OPT_ALIAS()'.

Thanks.
