        * tree-ssa-strlen.c (handle_store): Clarify return value meaning
        in function comment.
        (strlen_check_and_optimize_call): Likewise.  For handle_printf_call
        calls, return !handle_printf_call rather than always returning true.
        (check_and_optimize_stmt): Describe return value meaning in function
        comment.  Formatting fix.

        * gcc.dg/tree-ssa/builtin-snprintf-10.c: New test.
