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.

Create a repo with some tags

  $ hg init repo
  $ cd repo
  $ echo initial > foo
  $ hg -q commit -A -m initial
  $ hg tag -m 'test tag' test1
  $ echo first > first
  $ hg -q commit -A -m first
  $ hg tag -m 'test2 tag' test2
  $ hg -q up -r 0
  $ echo newhead > newhead
  $ hg commit -A -m newhead
  adding newhead
  created new head

Trigger tags cache population by doing something that accesses tags info

  $ hg log -G -T '{rev}:{node|short} {tags} {desc}\n'

Create some hidden changesets via a rebase and trigger tags cache
repopulation

  $ hg -q rebase -s 1 -d 4
