Right.  I was planning to do that, and also to make some trivial
reformatting in the backend's scan.l to make it easier to compare the
two files by diff.  For example, consistently write

    pattern        {
              action;
            }

not

    pattern        { action; }

so that the diffs are confined to the action lines.
