Fix if arguments contain ")" - possible for strings

[kunwar24]

In my case, I needed to pass a string as a parameter that contained values such as "(test)". The code was failing as it terminated the search for arguments at the first ")".

I can see that this helps for your specific case where the function arguments might, themselves, contain a ), but of course the argument list will also get messed up if they contain a comma. It's probably better if this logic is modified to cater for all the potential scenarios.
