revset-limit: use boolean testing instead of `len(revs) < 1`

I'm not sure why we wrote it that way. But smartsets have faster/lazier non-zero
testing than length computation.

  $ hg init
  $ echo This is file a1 > a
  $ hg add a
  $ hg commit -m "commit #0"
  $ ls
  a
  $ echo This is file b1 > b
  $ hg add b
  $ hg commit -m "commit #1"
  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

B should disappear

  $ ls
  a
