(allout-regexp, allout-line-boundary-regexp)

(allout-bob-regexp): Correct grouping and boundaries to fix backwards traversal.
(allout-depth-specific-regexp, allout-depth-one-regexp): New versions that
exploit \\{M\\} regexp syntax, to avoid geometric or worse time in
allout-ascend.
(allout-doublecheck-at-and-shallower): Identify depth threshold below which
topics are checked for and disqualified by containment discontinuities.
(allout-hotspot-key-handler): Correctly handle multiple-key strokes.  Remove
some unused variables.
(allout-mode-leaders): Clarify that mode-specific comment-start will be used
(set-allout-regexp): Correctly regexp-quote allout regexps to properly accept
alternative header-leads and primary bullets with regexp-specific characters
(eg, C "/*", mathematica "(*").
Include new regular expressions among those configured.
(allout-infer-header-lead-and-primary-bullet): Rename allout-infer-header-lead.
(allout-recent-depth): Manifest as a variable as well as a function.
(allout-prefix-data): Simplify into an inline instead of a macro, assuming
current match data rather than being explicitly passed it.  Establish
allout-recent-depth value as well as allout-recent-prefix-beginning and
allout-recent-prefix-end.
(allout-aberrant-container-p): True when an item's immediate offspring
discontinuously contained.  Useful for disqualifying unintended topic prefixes,
likely at low depths.
(allout-goto-prefix-doublechecked): Elaborated version of allout-goto-prefix
which disqualifies aberrant pseudo-items.
(allout-pre-next-prefix): Layer on top of lower-level routines, to get
disqualification of aberrant containers.
(allout-end-of-prefix, allout-end-of-subtree): Disqualify aberrant containers.
(allout-beginning-of-current-entry): Position at start of buffer when in
container (depth 0) entry.
(nullify-allout-prefix-data): Invalidate allout-recent-* prefix data.
(allout-current-bullet): Strip text properties.
(allout-get-prefix-bullet): Use right match groups.
(allout-beginning-of-line, allout-next-heading): Disqualify aberrant containers.
(allout-previous-heading): Disqualify aberrant containers, and change to
regular (rather than inline) function, to allow self-recursion.
(allout-get-invisibility-overlay): Increment so progress is made when the first
overlay is not the sought one.
(allout-end-of-prefix): Disqualify aberrant containers.
(allout-end-of-line): Cycle something like allout-beginning-of-line.
(allout-mode): Make allout-old-style-prefixes (ie, enabling use with outline.el
outlines) functional again.  Change the primary bullet along with the
header-lead - level 1 new-style bullets now work.
Engage allout-before-change-handler in mainline emacs, not just xemacs, to do
undo handling.
(allout-before-change-handler): Expose undo changes occurring in hidden
regions.  Use allout-get-invisibility-overlay instead of reimplementing it
inline.
(allout-chart-subtree): Use start rather than end of prefix in charts.  Use
allout-recent-depth variable.
(allout-chart-siblings): Disqualify aberrant topics.
(allout-beginning-of-current-entry): Position correctly.
(allout-ascend): Use new allout-depth-specific-regexp and
allout-depth-one-regexp for linear instead of O(N^2) or worse behavior.
(allout-ascend-to-depth): Depend on allout-ascend, rather than reimplementing
an algorithm.
(allout-up-current-level): Depend on allout-ascend, rather than reimplementing
an algorithm.  Return to start-point if we fail.
(allout-descend-to-depth): Use allout-recent-depth variable instead of function.
(allout-next-sibling): On traversal of numerous intervening topics, resort to
economical allout-next-sibling-leap.
(allout-next-sibling-leap): Specialized version of allout-next-sibling that
uses allout-ascend cleverly, to depend on a regexp search to leap large numbers
of contained topics, rather than arbitrarily many one-by-one traversals.
(allout-next-visible-heading): Disqualify aberrant topics.
(allout-previous-visible-heading): Position consistently when interactive.
(allout-forward-current-level): Base on allout-previous-sibling rather than
 (differently) reimplmenting the algorithm.  Remove some unused variables.
(allout-solicit-alternate-bullet): Present default choice stripped of text
properties.
(allout-rebullet-heading): Use bullet stripped of text properties.
Register changes using allout-exposure-change-hook.  Disregard aberrant topics.
(allout-shift-in): With universal-argument, make topic a peer of it's former
offspring.  Simplify the code by separating out allout-shift-out functionality.
(allout-shift-out): With universal-argument, make offspring peers of their
former container, and its siblings.  Implement the functionality here, rather
than inappropriately muddling the implementation of allout-shift-in.
(allout-rebullet-topic): Respect additional argument for new parent-child
separation function.
(allout-yank-processing): Use allout-ascend directly.
(allout-show-entry): Disqualify aberrant topics.
(allout-show-children): Handle discontinuous children gracefully, extending the
depth being revealed to expose them and posting a message indicating the
situation.
(allout-show-to-offshoot): Remove obsolete and incorrect comment.  Leave cursor
in correct position.
(allout-hide-current-subtree): Use allout-ascend directly.  Disqualify aberrant
topics.
(allout-kill-line, allout-kill-topic): Preserve exposure layout in a way that
the yanks can restore it, as used to happen.
(allout-yank-processing): Restore exposure layout as recorded by allout-kill-*,
as used to happen.
(allout-annotate-hidden, allout-hide-by-annotation): New routines for preseving
and restoring exposure layout across kills.
(allout-toggle-subtree-encryption): Run allout-exposure-change-hook.
(allout-encrypt-string): Strip text properties.  Rearranged order and
outline-headings for some of the miscellaneous functions.
(allout-resolve-xref): No need to quote the error name in the condition-case
handler section.
(allout-flatten): Classic recursive (and recursively intensive, without
tail-recursion) list-flattener, needed by allout-shift-out when confronted with
discontinuous children.
