Modified files:
	src            : scan-gram.l 

Log message:
	Include "files.h".
	(YY_USER_INIT): Initialize scanner_cursor instead
	of *loc.
	(STEP): Remove.  No longer needed, now that adjust_location does
	the work.  All uses removed.
	(scanner_cursor): New var.
	(adjust_location): Renamed from extend_location.  It now sets
	*loc and adjusts the scanner cursor.  All uses changed.
	Don't bother testing for CR.
	(handle_syncline): Remove location arg; now updates scanner cursor.
	All callers changed.
	(unexpected_end_of_file): Now accepts start boundary of token or
	comment, not location.  All callers changed.  Update scanner cursor,
	not the location.
	(SC_AFTER_IDENTIFIER): New state.
	(context_state): Renamed from c_context.  All uses changed.
	(id_loc, code_start, token_start): New local vars.
	(<INITIAL,SC_AFTER_IDENTIFIER>): New initial context.  Move all
	processing of Yacc white space and equivalents here.
	(<INITIAL>{id}): Save id_loc.  Begin state SC_AFTER_IDENTIFIER
	instead of returning ID immediately, since we need to search for
	a subsequent colon.
	(<INITIAL>"'", "\""): Save token_start.
	(<INITIAL>"%{", "{", "%%"): Save code_start.
	(<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
	(<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
	BEGIN context_state at end, not INITIAL.
	(<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
	<SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
	Return correct token start.
	(<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
	the start of a character, string or multiline comment is found.
