Do you literally mean "a path to a repository" in the above, or do you mean "a remote that is like what is accepted by 'git fetch'"? If you literary mean it is is a path to a git repository, you could obviously use "cd $there && git rev-parse --git-dir" or something. On the other hand, if you mean the command takes a remote and an optional list of refspecs just like "git fetch" does, then I am not sure it is a good design in the first place to allow "refspecs only", if only to keep the interface similar to "git fetch" (you cannot omit remote and give refspecs, as you cannot interpret refspecs without knowing in the context of which remote they are to be interpreted). I would imagine you could disambiguate and default to "origin" or something when you guessed that remote was omitted if you really wanted to, with a syntacitical heuristics, such as "a refspec will never have two colons in it", "a URL tends to begin with a short alphabet word, a colon and double-slash", etc. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
