Hi,
Thanks, I've applied your patch with one small fix,
The else block at the end of was wrongly indented
(one indent level too much) It is the else for the first if, not the second.
Note the first if has a { at the end of the line, and the second does not,
and the else starts with a }.
Regards,
Hans
