[CLEANUP PATCH] show <tag>: reuse pp_user_info() instead of duplicating code

[Johannes Schindelin <Johannes.Schindelin@gmx.de>]

We used to extract the tagger information "by hand" in "git show <tag>",
but the function pp_user_info() already does that.  Even better:
it respects the commit_format and date_format specified by the user.

	Just a little cleanup, as I tripped over that part of Git's source.
