+ * allout.el (allout-expose-topic): Rectify implementation of "+"
+ spec, so that bodies are not exposed with headlines.
+
+2006-10-01 Ken Manheimer <ken.manheimer@gmail.com>
+
+ * allout.el (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.
