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

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
