Merge branch 'js/for-each-ref-remote-name-and-ref'

The "--format=..." option "git for-each-ref" takes learned to show
the name of the 'remote' repository and the ref at the remote side
that is affected for 'upstream' and 'push' via "%(push:remotename)"
and friends.

* js/for-each-ref-remote-name-and-ref:
  for-each-ref: test :remotename and :remoteref
  for-each-ref: let upstream/push report the remote ref name
  for-each-ref: let upstream/push optionally report the remote name

no effect if the ref does not have tracking information

For any remote-tracking branch `%(upstream)`, `%(upstream:remotename)`
and `%(upstream:remoteref)` refer to the name of the remote and the
name of the tracked remote ref, respectively. In other words, the
remote-tracking branch can be updated explicitly and individually by
using the refspec `%(upstream:remoteref):%(upstream)` to fetch from
`%(upstream:remotename)`.

push::
The name of a local ref which represents the `@{push}`
location for the displayed ref. Respects `:short`, `:lstrip`,
`:rstrip`, `:track`, and `:trackshort` options as `upstream`
does. Produces an empty string if no `@{push}` ref is
configured.
