revset: use `subset &` in `divergent`

This takes advantage of the `fullreposet` smartness.

revset #0: divergent()
0) wall 0.002047 comb 0.000000 user 0.000000 sys 0.000000 (best of 813)
1) wall 0.000052 comb 0.000000 user 0.000000 sys 0.000000 (best of 22757)

  $ hg init

  $ echo a > a
  $ hg ci -qAm 'add a'

  $ hg init subrepo
  $ echo 'subrepo = http://example.net/libfoo' > .hgsub
  $ hg ci -qAm 'added subrepo'

  $ hg up -qC 0
  $ echo ax > a
  $ hg ci -m 'changed a'
  created new head

  $ hg up -qC 1
  $ cd subrepo
  $ echo b > b
  $ hg add b
  $ cd ..

Should fail, since there are added files to subrepo:

  $ hg merge
  abort: uncommitted changes in subrepository 'subrepo'
