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

# Dummy extension to define a namespace containing revision names

from __future__ import absolute_import

from mercurial import (
    namespaces,
)

def reposetup(ui, repo):
    names = {'r%d' % rev: repo[rev].node() for rev in repo}
    namemap = lambda r, name: names.get(name)
    nodemap = lambda r, node: ['r%d' % repo[node].rev()]

    ns = namespaces.namespace('revnames', templatename='revname',
                              logname='revname',
                              listnames=lambda r: names.keys(),
                              namemap=namemap, nodemap=nodemap)
    repo.names.addnamespace(ns)
