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.
