[PATCH v2 2/2] request-pull: state exact commit object name

[Junio C Hamano <gitster@pobox.com>]

A typical pull-request begins like this:

  The following changes since commit f696543dad6c7ba27b0c4fab167a5687263a9ba0:

    Flobar 2.4.3 (2011-09-13 12:34:56 +0900)

  are available in the git repository at:
    git://git.kernel.org/pub/flobar.git/ master

which is followed by the shortlog and expected diffstat. This tells you
where the requester based his work on in excruciating detail, but does not
tell you what you should expect to fetch, any more than "whatever happened
to be at the named branch when you happened to notice the request."

Update the message slightly to say:

    git://git.kernel.org/pub/flobar.git/ 5738c9c21e53356ab5020912116e7f82fd2d428f ;# master

so that the line still can be cut&pasted after "git fetch" (or "git
pull"), to form a command line that looks like:

    $ git <repository> <full commit object name> ;# branch
