[PATCH 0/4] Support triangular workflows

Hi,

This series follows up a previous discussion with Junio and Jeff [1].
It attempts to support the triangular workflow, where the remote
you're fetching from is not the same as the remote you're pushing to.
`remote.<name>.pushurl` has already been discussed, and deemed as a
poor solution to the problem [2].

[1/4] is a minor cleanup patch to make other patches consistent with
the existing style.

[2/4] introduces the infrastructure needed to allow [3/4] and [4/4] to
be simple configuration-adding patches.

[3/4] and [4/4] add the proposed configuration options.  They're very
simple patches, but the documentation is not so simple: I've
documented all the side-effects of the other configuration option in
each configuration option, to give the reader a comprehensive picture
when reading one configuration option.

I've put off implementing remote.default corresponding to
remote.pushdefault, as Jeff suggested in [1], because it's currently
not an itch; apart from the obvious symmetry, I don't know what
purpose it serves: why would anyone want to fetch from a remote other
than origin by default?  Why wouldn't they simply swap that remote's
name with "origin"?  However, it's a nice thing to have for symmetry,
and it should be trivial to implement: any interested person is
welcome to pick it up.

The series works as expected, and all tests pass.

Thanks for reading.
