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.

See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with XEmacs. If not, see <http://www.gnu.org/licenses/>. This directory contains a number of XEmacs dynamic modules. These modules can be loaded directly with the command 'M-x load-module'. However, the preferred method of loading a module is to issue a "(require 'module-name)" command to the Lisp interpreter. This will store information so that a later "(unload-feature 'module-name)" can succeed. To compile one of these modules, simply enter the desired directory, type 'configure', and then 'make'. If you are building the module for an installed XEmacs, then 'make install' will place the module in the appropriate directory for XEmacs to find it later (assuming you have permission to write to that directory). A subsequent 'load-module' or 'require' will then load the module, as described above. Each of these demonstrates different features and limitations of the XEmacs module loading technology. For a complete discussion on XEmacs dynamic modules, please consult the XEmacs Module Writers Guide, which can be found in the ../info directory. For those wanting to get started with module writing, please see the 'sample' directory. It contains two subdirectories: internal and external. The 'internal' subdirectory contains the framework needed to migrate some core piece of XEmacs functionality into code that can either be compiled into the core or built as a separate module. The 'external' subdirectory contains the somewhat simpler framework needed to build a module separately from XEmacs. These should be considered starting places for module writing.
