+
+	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.
