Fix performance regression in refactored syntax cache setup.
More doc improvements.
* syntax.h (enum syntax_source):
New. Specify whether syntax is from property or buffer.
(struct syntax_cache):
Use enum syntax_source source, instead of no_syntax_table_prop
and use_code.
Improve comments.
(SOURCE_IS_TABLE):
New predicate.
(SYNTAX_CODE_FROM_CACHE):
Use it instead of use_code, and adjust logic.
* syntax.c (syntax_cache_table_was_changed):
Check cache->source (cache->no_syntax_table_prop is gone).
(reset_syntax_cache_range):
All information about OBJECT and BUFFER is in CACHE already.
Also reset markers in OBJECT if it is a buffer.
Rename INFINITE to VALID_EVERYWHERE.
(init_syntax_cache):
Initialize source (cache->no_syntax_table_prop is gone).
Maybe initialize start and end to null markers.
Initialize cache range with reset_syntax_cache_range.
(update_syntax_cache):
Use source instead of no_syntax_table_prop and use_code.
(setup_syntax_cache):
Add header comment. Improve other comments.
Make calls to reset_syntax_cache_range and init_syntax_cache match
their prototypes.
(init_buffer_syntax_cache):
Use init_syntax_cache to do the work.
(signal_syntax_cache_extent_changed):
Make call to reset_syntax_cache_range match its prototype.
Improve local variable naming.

\input /home/gd/gnu/doc/texinfo.tex @c -*-texinfo-*- @c %**start of header @setfilename ../../info/back-cover @settitle XEmacs Lisp Reference Manual @c %**end of header . @sp 7 @center @titlefont {XEmacs Lisp} @sp 1 @quotation Most of the XEmacs text editor is written in the programming language called XEmacs Lisp. You can write new code in XEmacs Lisp and install it as an extension to the editor. However, XEmacs Lisp is more than a mere ``extension language''; it is a full computer programming language in its own right. You can use it as you would any other programming language. Because XEmacs Lisp is designed for use in an editor, it has special features for scanning and parsing text as well as features for handling files, buffers, displays, subprocesses, and so on. XEmacs Lisp is closely integrated with the editing facilities; thus, editing commands are functions that can also conveniently be called from Lisp programs, and parameters for customization are ordinary Lisp variables. This manual describes XEmacs Lisp. Generally speaking, the earlier chapters describe features of XEmacs Lisp that have counterparts in many programming languages, and later chapters describe features that are peculiar to XEmacs Lisp or relate specifically to editing. @end quotation @hfil @bye
