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.
(tags-next-table): Save tags-table-list in tags-table-parent-pointer-list
and then set it to tags-included-tables.
Restore tags-table-list from tags-table-parent-pointer-list.
(tags-find-table-in-list): Renamed from tags-table-list-member.
Search included tables. Take new arg MOVE-TO; if t, frob list pointers.
(tags-table-including): Save tags-table-list in tags-table-parent-pointer-list.
Set tags-table-list to the passed TABLES value.
(visit-tags-table-buffer): When CONT is nil, pop all
tags-table-parent-pointer-list state before doing anything else.
Don't do list frobnication when CONT is 'same.
Call tags-find-table-in-list instead of tags-table-list-member; let it do
list frobnication when it succeeds.
Rename the args. Compute x and y fields from negative positions.
Use XGetWMNormalHints if X11R4 or newer.
(x_make_frame_visible): Call x_set_offset only if not USE_X_TOOLKIT.
(x_make_frame_invisible): Call x_wm_set_size_hint.
(x_set_offset): Pass 0 as 3rd arg to x_wm_set_size_hint.
(x_set_window_size): Likewise. Set win_gravity field here if nec.
