dagop: change revdescendants() to include all root revisions

Prepares for adding depth support. I want to process depth=0 in
revdescendants() to make things simpler.

only() also calls dagop.revdescendants(), but it filters out root revisions
explicitly. So this should cause no problem.

  # descendants(0) using hg repo
  0) 0.052380
  1) 0.051226

  # only(tip) using hg repo
  0) 0.001433
  1) 0.001425

  $ hg init a
  $ cd a
  $ echo 123 > a
  $ hg add a
  $ hg commit -m "a" -u a

  $ cd ..
  $ hg init b
  $ cd b
  $ echo 321 > b
  $ hg add b
  $ hg commit -m "b" -u b
