narrow: make dirstateguard back up and restore working copy narrowspec instead...

narrow: make dirstateguard back up and restore working copy narrowspec instead We used to have only one narrowspec for the store and the working copy, but now that we have one narrowspec for each, it seems clear that the dirstateguard was supposed to back up and restore the narrowspec associated with the working copy, not the one associated with the store. clearbackup() (for the store narrowspec) is not needed because the presence of the file in localrepository._journalfiles() takes care of that.

      # produces two repositories with different common and missing subsets

      #

      #   $ discovery-helper.sh REPO NBHEADS DEPT

      #

      # The Goal is to produce two repositories with some common part and some

      # exclusive part on each side. Provide a source repository REPO, it will

      # produce two repositories REPO-left and REPO-right.

      #

      # Each repository will be missing some revisions exclusive to NBHEADS of the

      # repo topological heads. These heads and revisions exclusive to them (up to

      # DEPTH depth) are stripped.

      #

      # The "left" repository will use the NBHEADS first heads (sorted by

      # description). The "right" use the last NBHEADS one.

      #

      # To find out how many topological heads a repo has, use:

      #

      #   $ hg heads -t -T '{rev}\n' | wc -l

      #

      # Example:

      #

      #  The `pypy-2018-09-01` repository has 192 heads. To produce two repositories

      #  with 92 common heads and ~50 exclusive heads on each side.

      #

      #    $ ./discovery-helper.sh pypy-2018-08-01 50 10
