Teach @{upstream} syntax to strbuf_branchanme() This teaches @{upstream} syntax to interpret_branch_name(), instead of dwim_ref() machinery. There are places in git UI that behaves differently when you give a local branch name and when you give an extended SHA-1 expression that evaluates to the commit object name at the tip of the branch. The intent is that the special syntax such as @{-1} can stand in as if the user spelled the name of the branch in such places. The name of the branch "frotz" to switch to ("git checkout frotz"), and the name of the branch "nitfol" to fork a new branch "frotz" from ("git checkout -b frotz nitfol"), are examples of such places. These places take only the name of the branch (e.g. "frotz"), and they are supposed to act differently to an equivalent refname (e.g. "refs/heads/frotz"), so hooking the @{upstream} and @{-N} syntax to dwim_ref() is insufficient when we want to deal with cases a local branch is forked from another local branch and use "forked@{upstream}" to name the forkee branch. The "upstream" syntax "forked@{u}" is to specify the ref that "forked" is configured to merge with, and most often the forkee is a remote tracking branch, not a local branch. We cannot simply return a local branch name, but that does not necessarily mean we have to returns the full refname (e.g. refs/remotes/origin/frotz, when returning origin/frotz is enough). This update calls shorten_unambiguous_ref() to do so. Signed-off-by: Junio C Hamano <gitster@pobox.com>
