patchrequest-pull: avoid mentioning that the start point is a single commit

Previously we ran shortlog on the start commit which always printed "(1)" after the start commit, which gives no information, but makes the output less easy to read. Avoid doing so.

So for example the 'git request-pull master~2 . master' output diff is the following here:

	 The following changes since commit 68186857a9bb0a71e9456155623e02d398a5b817:
	-  Junio C Hamano (1):
	-        Merge branch 'il/maint-colon-address'
	+  Junio C Hamano: Merge branch 'il/maint-colon-address'

Nice fix, that was annoying me too, but I didn't care enough to
write a patch.  :-)

A few comments:

 - Modernising implementation by using tools different from what the
   original used (i.e. shortlog -> log) is fine, but I'd recommend doing
   so even more thoroughly.  Use "show -s" instead of "log -1" and
   "--format=" instead of "--pretty=format:", for example.

 - If the stated goal of the change is to remove " (1)" which is
   distracting with no useful information, remove that and only that,
   without changing anything else in the output.

 - On the other hand, if you find that "AuthorName: " part is less useful
   in identifying the commit than its title to help the requestee, change
   the whole thing to make it even more useful.

So I'd suggest either:

	git show -s --format="  %an:%n        %s" $baserev

to be conservative, or

	git show -s --format="  %s (%an)" $baserev

or even to this:

	git show -s --format="  %s (%ci)" $baserev

I suspect that the last one would be the easiest for the requestee to judge the freshness of the branch.

Why isn't the "The following changes..." line not part of the --format thing, by the way? From the POV of readability of the code (not necessarily the output), doing it this way might be the cleanest:

-- >8 -- git show -s --format='The following changes since %H

    %s (%ci)

are available in the git repository at:' $baserev echo " $url $branch" -- 8< --

OK, I changed it accordingly, though I did not the change the output of the "commit <hash>" line. So the output diff is:
