REVISION SUMMARY
  I couldn't think of a reason that we need to check state files on disk
  to determine if a merge is active. I could imagine them being for
  there for detecting broken state files that would then be cleaned up
  by some later command, but we always delete the entire `.hg/merge/`
  tree, so that doesn't seem to be it.
  
  The checks were added in 4e932dc5c113 
 
(resolve: abort when not
  applicable (BC), 2014-04-18). Perhaps there were needed for that and
  then made obsolete by 6062593d8b06 
 
(resolve: don't abort resolve -l
  even when no merge is in progress, 2014-05-23).
  
  The reason I want to delete the checks is that I think `ms =
  mergestate.read(repo); ms.active() and ms.local` should be a valid
  pattern, but it crashes when the merge state file is an empty file if
  we consider mere presence of the file as "active".
