I would speculate that `git checkout -` may have learned about "-"
simply from the `cd -` ...

You do not have to speculate.  You only need to read what has been
already said in the thread ;-).

Should I expect "git checkout ~" to get me to my "home" branch then? ;-)

Heh, no you shouldn't: the '~' is expanded by the shell itself according
to its parameter expansion rules, so `cd` never sees the bare tilde
in this case ;-)

Yeah, but then git could compare its argument to $HOME and "do the right
thing" ;-) Just kidding, obviously.

That said, bare "cd" also changes to home directory, so bare "git
checkout" could become as useful.

My qualms about the general usefulness of a bare 'git checkout' going to
some bookmarked branch aside, this won't work, since a bare 'git
checkout' already sets HEAD to the currently checked-out branch.

That said, I am not at all sold on this being a good idea.

Actually, that could be a good idea. I mean, to have "home" branch
notion and a short-cut for it.

I have no say for the idea per se but you would have hard time using
bare tilda character for that precisely because of it being special to
Unix shells - you'd need to escape it all the time (though something
like unquoted @{~} would work just OK).

Yes, plain '~' won't do.
