PR/51517: Jay West: Tty settings not restored on exit
PR/51518: Jay West: prompt is interleaved with client output

Both these issues are caused by rl_restore_handler not DTRT; fix
it so that it kills the internal libedit state completely. This is
inefficient, but it works.

Also fix:
1. add append_history()/H_NSAVE_FP
2. call the rl_startup_hook before printing the first prompt as documented.
callint it from rl_initialize breaks python, because the callback ends
up being invoked before the readline module is installed, and we end up
dereferencing a NULL pointer.
3. add el_resize_terminal.

With those changes, s/lreadline/ledit/g in python works.

Remove workaround for ancient HTML generation code.

documentation improvements (Ingo Schwarze)

Fix the prototype used by EL_GETCFN, mention the associated typedef
name, document the return values, expand the list of affected
functions, warn against using EL_GETCFN, and clarify some wording
and notation. (Ingo Schwarze)

GNU readline(3) regards history chronologically, that is, from the
perspective of the dawn of time, so "next" means "newer" and "previous"
means "older". Libedit, by contrast, uses reverse chronology and
regards history from the perspective of the present, such that "next"
means "longer ago" and "previous" means "not so long ago".

The following patch fixes previous_history() and next_history()
as proposed by Bastian Maerkisch.

But there is a related problem demonstrated by Bastian's regression
tests that his patch did not fix: next_history() can advance not
only to the newest entry, but beyond it, which core libedit cannot
do. So that feature must be implemented locally in readline.c.

With that, the last of Bastians tests is fixed, test_movement_direction().

This patch also improves libedit documentation to more clearly state
what "previous" and "next" mean. GNU readline documentation is
just as unclear, but we can't easily fix that since libedit doesn't
include its own readline.3 manual.

Fix descriptions of el_set functions.
Americanise initialise :-)

Bump date for previous.

From Ingo Schwarze, based on changes from Kaspars Bankovskis:
* Document error handling of el_init(), el_set(), el_source(),
and history_init().
* Fix a typo an improve punctuation below H_SETUNIQUE.
* The ellipsis already implies "optional", no need for [].
* Sort options in editrc(5).
* Prevent e.g. rom being misconstrued as the end of a sentence.
* Drop a useless duplicate .Ar macro.
* Put telltc in its proper place in the alphabetical order.
* A few typos in vi editor command names.
* Some missing vi editor command names.
* Some missing author macros.

Punctuation nit.

Don't use .Xo/.Xc to avoid ancient macro argument limit.

Readability improvement. Whitespace nits.

Implement literal prompt sequences. Now someone can implement
RL_PROMPT_START_LITERAL/RL_PROMPT_END_LITERAL :-)

-1 is not a defined value, it is just a value.
On the other hand, minuses need backslashes, otherwise they become hyphens.

error.

Tokenization function enhancements:
* Make tok_init(), tok_end(), tok_reset(), tok_line() and tok_str()
publically available in <histedit.h>
* Documented the public functions in editline(3)
* Renamed tok_line() -> tok_str()
* Added new tok_line() which takes a "const LineInfo *" instead of
"const char *" (the former has "cursor" information), and optionally
return the argv index ("int *cursorc") and offset within that index
("int *cursorv"). This means that completion routines can use the
tokenization code to crack the line and easily find which word the
cursor is at. (mmm, context sensitive completion :)
* Fixed TEST/test.c when using "continuation" lines (unmatched quote
or \ at EOL), and added some more DEBUG messages including highlighting
where the cursor is (with a `_').

- implement printing a right-side prompt. code derived from similar work
I wrote for tcsh(1) three years ago.
- implement EL_RPROMPT, which allows a setting/getting of a function which
returns a string to be used as the right-side prompt.
- improve HISTORY and AUTHORS sections in editline(3).
- bump shlib minor version for EL_RPROMPT.

XXX: due to an implementation issue, the rprompt has a 1 space gap before the
edge of the logical screen. editline's logical screen is 1 space less
than the full screen width, so there's a 2 space gap between the rprompt
and the right end of the physical screen. i'm not concerned about this.

More trailing white space.

Last of the .Os cleanups. .Os is defined in the tmac.doc-common file,

fix history() prototype. (d@openbsd.org)

* add more checks for NULL pointers in passed arguments
* implement el_get(EditLine *, int op, void *result), which does the
inverse of el_set()
* add EL_EDITMODE operation to el_set and el_get; if non zero editing
is enabled (the default).
* add "edit on | off" editrc command, which modifies EL_EDITMODE.
users can now add '*:edit off' in ~/.editrc as an advisory to
disable editing.

NOTE: at this time EL_EDITMODE is just an indication of the
state of the 'edit' command. It's up to the application to check
this after el_source() or el_parse() to determine if editing is still
required.

documentation is always probably incomplete; don't make an issue of it

* implement CC_REFRESH_BEEP; as per CC_REFRESH but beep as well. this
is useful in completion when a partial completion is found
* remove entry in BUGS about el_parse(); that was fixed a while ago

Add H_APPEND to simplify the interface.

Implement CC_REDISPLAY, which (unlink CC_REFRESH) redraws the entire input
