  From my vague memory, I guess I would think that if we do `s/ctx.files()/ctx/`
  (which means we're looking for revisions where files exist, not files change),
  the use of `walkfilerevs()` is not valid since filelogs only contain "changes."
  
  To be clear, I'm not saying that will be the desired behavior of `hg grep` of
  "--all-files" of multiple revisions. It might be better to skip intermediate
  revisions where files are unchanged.
