This patch offers the new suffix :remote for the upstream and for the push atoms, allowing to show exactly that.
Has the design changed since this description and examples were written? The documentation talks about ":remote-name". I suspect calling this ":remote" might be less hassle, as we do not have to vet the current vocabulary to see if "remote-name" is the right way to name a multi-word modifer (as opposed to "remotename", or "remoteName", or "remote_name", or...).

Aside from "':remote-name'? Do we really want that?" issue I already mentioned, the changes to this file look sensible.

I think "int explicit = 0;" is needed, as pushremote_for_branch() does seem to expect that the "explicit" return parameter is initialized by the caller.

This one is debatable. For the user of "push" who wants to learn where the branch is pushed to, the choice this patch makes is not useful (i.e. such a user does not care where the definition comes from; s/he only wants to know where the push goes). For the user of "git config" who wants to know how pushremote is configured, and does not want to accept the fallback to remote, the behaviour of this patch is useful. I have a mild suspicion that majority of users who would want to use this feature would fall into the former category, i.e. users of "push", rather than the latter, i.e. debuggers of their config files, and if that is true, we can drop the whole "explicit" business to simplify the code and get a more useful behaviour at the same time ;-)

I am not sure what is going on here. Are we expecting "push:remote-name" here, or anticipating "push:remote-bar" can also be given or what?
