delta-find: split the "sparse" part of `_pre_filter_rev` in a method

Since `_pre_filter_rev` contains logic from various sources of constraint, we
start splitting is in subfunction to clarify and document the grouping.

  $ hg help cleanstatus
  hg cleanstatus [ONLYHELPHERE]
  
  alias for: hg status -c
  
  show changed files in the working directory
  
      Show status of files in the repository. If names are given, only files
      that match are shown. Files that are clean or ignored or the source of a
      copy/move operation, are not listed unless -c/--clean, -i/--ignored,
      -C/--copies or -A/--all are given. Unless options described with "show
      only ..." are given, the options -mardu are used.
  
      Option -q/--quiet hides untracked (unknown and ignored) files unless
      explicitly requested with -u/--unknown or -i/--ignored.
  
      Note:
         'hg status' may appear to disagree with diff if permissions have
         changed or a merge has occurred. The standard diff format does not
         report permission changes and diff only reports changes relative to one
         merge parent.
  
      If one revision is given, it is used as the base revision. If two
      revisions are given, the differences between them are shown. The --change
      option can also be used as a shortcut to list the changed files of a
      revision from its first parent.
  
      The codes used to show the status of files are:
  
        M = modified
        A = added
        R = removed
        C = clean
        ! = missing (deleted by non-hg command, but still tracked)
        ? = not tracked
        I = ignored
          = origin of the previous file (with --copies)
  
      Returns 0 on success.
