There are times when scripts want to know not only the name of the push branch on the remote, but also the name of the branch as known by the remote repository. An example of this is when a tool wants to push to the very same branch from which it would pull automatically, i.e. the `<remote>` and the `<to>` in `git push <remote> <from>:<to>` would be provided by `%(upstream:remotename)` and `%(upstream:remoteref)`, respectively. This patch offers the new suffix :remoteref for the `upstream` and `push` atoms, allowing to show exactly that. Example: $ cat .git/config ... [remote "origin"] url = https://where.do.we.come/from fetch = refs/heads/*:refs/remote/origin/* [branch "master"] remote = origin merge = refs/heads/master [branch "develop/with/topics"] remote = origin merge = refs/heads/develop/with/topics ... $ git for-each-ref \ --format='%(push) %(push:remoteref)' \ refs/heads refs/remotes/origin/master refs/heads/master refs/remotes/origin/develop/with/topics refs/heads/develop/with/topics Signed-off-by: J Wyman <jwyman@microsoft.com> Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
