fetch,parse-remote,fmt-merge-msg: refs/remotes/* support

We can now easily fetch and merge things from heads in the
refs/remotes/ hierarchy in remote repositories.

The refs/remotes/ hierarchy is likely to become the standard for
tracking foreign SCMs, as well as the location of Pull: targets
for tracking remote branches in newly cloned repositories.
