[RFC/PATCH] pack-refs --all

[Junio C Hamano <junkio@cox.net>]

This changes 'git-pack-refs' to pack only tags by default.
Branches are meant to be updated, either by committing onto it
yourself or tracking remote branches, and packed entries can
become stale easily, but tags are usually "create once and live
forever" and benefit more from packing.
