(Scomment_fence, Sstring_fence): New delimeter char classes
denoted by `!' and `|'.
(Fchar_syntax, Fmatching_paren): Update gl_state to whole-bufferstate.
(scan_words): update gl_state when needed.
(Fskip_chars_forward): Move from search.c.
(Fskip_chars_backward): Move from search.c.
(Fskip_syntax_forward): Move from search.c.

parenthesis.

Initialize Vstandard_syntax_table by share objects in
Vsyntax_code_object.
(syms_of_syntax): Staticpro Vsyntax_code_object.
(Fmodify_syntax_entry, init_syntax_once): Use SET_RAW_SYNTAX_ENTRY.
Handle new syntax-table data format.
(check_syntax_table): Use CHECK_CHAR_TABLE. Now static.
Don't return anything; callers changed.
