So what do I need to do.

-Close the patch and wait for someone to do the larger fix to all functions.
- Just change this function but then what needs to be changed in it.

I am not familiar enough with Regular Expressions to know how to add an 
extra * if it is needed so that the user does not have to do it.

Someone needs to help me with a suggestion about this or else someone 
else needs to pick up this bug and associated patch.

Regards,
Adolf.
