Yeah, I was completely blind here, that should definitely have been
updated as well.  Thanks for catching.

The best advice for it might indeed be different for "save" and
"push".  The slight weirdness we have here is that both "save" and
"push" are using the same option parsing.

Now that we're deprecating "save", I don't think it's worth the effort
to try to get rid of this weirdness.

I think using "--" to distinguish the the pathspec from the command
line options is a common enough pattern that we don't need to give
advice to the users.  I feel like that second line was mostly there
because of the weirdness in the user interface for "stash save".
Maybe we should just get rid of that part alltogether?
