The script is based on regular expressions; hence things like nested 
parenthesis expressions are not possible to express with it. This is what 
causes your problems. There is limited support for converting those 
expressions, but as soon as you use parentheses within parentheses, it 
doesn't work anymore.

AFAIK there are no short-term plans to fix this.
