Do you mean, by "save typing", "instead of origin/master, I can type
master"?

If you are using the "checkout -t -b topic origin/master", "git rebase"
without any other argument should know that you meant to rebase
against 'origin/master', so you do not even have to type 'master'.

Yup, that is sensible, and I think with Felipe's proposed change,
you can spell it like this:

    [branch "topic"]
	remote = origin
	merge = refs/heads/master
        push = refs/heads/kbracey/topic

Note that the above assumes you did "checkout -t -b topic origin/master"
as a typesaver for "git rebase".

Understood.  And I think the [branch "topic"] configuration above
would cover that use case.

"git pull --rebase" would be "git fetch" followed by "git rebase",
and again the [branch "topic"] configuration above would cover that
use case, I think.

I think checkout and branch is already covered with -t.  There may
even be a configuration option to implicitly add -t to them (I
didn't check).

Yeah, I would imagine that it would be trivial to add an option to
cause "git push" to do that, and it would be useful if you push to
and pull from the same place (I haven't thought about ramifications
such an option would have on the triangular workflows, though).

Thanks.
