Ah, that is an excellent example that can be used to strengthen the
motivation part of this commit.

    A user may want to clone only "refs/pull/$n/head" to take a
    peek, but unlike refs/heads/ and refs/tags/, for which the
    "--branch" option can be used, there is no good simple way to do
    so with "git clone".

would make a good intro paragraph for a proposed log message.

Yes, not seeing refs/pull/ without being told was slight lack of
imagination on my part, but it is a good idea to spell out the
motivation in concrete terms when we can.

Thanks.
