"git -p cmd" to page anywhere
This allows you to say: git -p diff v2.6.16-rc5.. and the command pipes the output of any git command to your pager. [jc: this resurrects a month old RFC patch with improvement suggested by Linus to call it --paginate instead of --less.] Signed-off-by: Junio C Hamano <junkio@cox.net>
