Which, btw, led me to consider whether there are heuristics for deciding
when a fetch refspec means one thing and not the other. I don't think
there are reliable ones (probably the default configured
refs/remotes/$remotename/* would not yield false positives, but I think
limiting to that would yield false negatives). So maybe this is
something that should be configurable, disabled by default for now, and
maybe enabled by default in the future (v1.7.0?).
