  Perhaps, it can be called a "rootglob".

  I don't remember how the discussion ended, but since we have new "rootfilesin"
  matcher, "root<whatever>" should be the new naming convention.

  Can you add a new matcher kind 'rootglob'? I understand 'glob' can be abused
  for .hgignore, but it's the pattern relative to cwd.
