allout bugfixes - small bugs in charts, exposure specs

[Ken Manheimer]

thanks are due bill white for uncovering and diagnosing some chart
bugs, and contributing a fix for one.  in addition, there's one loose
end repaired for the recently introduced aberrant-topics provisions.

        (allout-current-depth): Do aberrent check only at or below
        doublecheck depth.
        (allout-chart-subtree): Make it explicit that LEVELS being nil
        means unlimited depth.  Drop undocumented support for LEVELS value
        t meaning unlimited depth.  (This is consistent with
        allout-chart-to-reveal, but contrary to allout-show-children,
        which needs to use nil to default to depth of 1.)
        (allout-goto-prefix-doublechecked): Wrap long docstring line.
        (allout-chart-to-reveal): Be explicit in docstring about meaning
        of nil LEVELS, and drop support for LEVELS value t.
        (allout-show-children): Translate the level spec used by this
        routine to that used by allout-chart-subtree and
        allout-chart-to-reveal.
        (allout-show-to-offshoot): Retry once when stuck, after opening
        subtree - improvements in discontinuity handling likely will
        enable progress.
        (allout-expose-topic): Rectify implementation of "+" spec, so that
        the subtrees are hidden and only the headlines are exposed.
        (Thanks to bill white for contributing this fix.)
