refinements, doc-string clarification and elaboration, etc.
Prominent new features include:
- Exposure changes and navigation are greatly accelerated.
- More elaborate and clear doc-string for outline-mode,
giving better guidance on use of the mode.
- A new exposure-layout syntax, which accomodates outlines
with multiple top-level topics. (See `outline-expose' and
`outline-new-exposure'.)
- Automatic exposure and verfication-prompting on attempts to
change text within concealed regions, before they are
applied. (Undo affecting concealed regions is only
exposed, not verified, to facilitate smooth undo sequences.)
- 'hot-spot' navigation implemented. When the cursor is on a
topic's bullet, regular-character keystrokes will be
interepreted as if they were preceded by ^C, when
appropriate, so users can navigate and adjust exposure,
etc, with single-stroke commands.
- Lucid emacs accomodated.
