Thanks you for the patch. Can you provide, in addition, a comment as to what
the 'brtl' option does and why it's needed, so that in future, folks reading
this file won't have to guess?
Also, should you send further patches, please use the unified diff format.
For this patch, I can manually apply it, but complex patches are useless without
context in diff.
Thanks,
Volodya
