log: make -fr show complete history from the given revs Right now it's very obtuse to show the history of a particular rev (hg log -r 'reverse(::foo)'). This changes the -f option to make it follow history for the revs specified by -r. The current -f -r behavior is to limit the result of -r to only the commits that are ancestors of the current working copy. Changing this is a bit of a BC break, but the old behavior is A) rare, B) easy to emulate (& ::.), and C) currently undefined. The new behavior is frequently requested enough that I think the change is worth it.
