+/* Theory of the syntax table cache
+
+ This cache cooperates with but is conceptually different from the
+ mirror table. The mirror table precomputes (and caches, if you like)
+ the syntax codes for characters in a given syntax table, taking into
+ account possible inheritance from a table given by a parent text object.
+ The syntax table cache checks for overriding tables defined by
+ _subobjects_.
+
+ This implementation defines the "subobjects" by _extent properties_.
+ We may restrict them to _text_ properties. There are two lookup
+ styles for the cache, "single code" and "full table". In the "single
+ code" style, a given syntax code, kept in the `syntax_code' member, is
+ applied to the entire range (#### check this). In the "full table"
+ style, a syntax table kept in the `current_syntax_table' member is
+ checked for each character in the range. If the flag `use_code' is
+ non-zero, the "single code" is used, otherwise the "full table".
+
+ The cache is valid for the range `[prev_change, next_change)' in the
+ text object (buffer or string) `object'.
+
+ If the current position is outside the range valid for the cache, the
+ cache is updated by checking for the text property `syntax-table'. If
+ present, its value is either a syntax code or a syntax table, and the
+ appropriate member and `use_code' are updated accordingly. If absent
+ or nil, the default syntax table from the `buffer' member is used. The
+ extent of the property is used to reinitialize the cache's validity
+ range. (We would like to improve this by checking the property value
+ against `old_prop', and if the same, extend the validity range of the
+ cache by the extent of the property.)
+
+ Note: the values Qt and Qnil for `object' are not supported in this
+ implementation. GNU Emacs uses them for reasons not yet (####) clear.
