Param reference inaccurate for argument flags

[astrovsky01]

When referencing a param that uses argument instead of name, the param generated replaces the "--" with underscores instead of removing them for the parameter reference

Thanks for reporting @astrovsky01!

I've just tried with a simple example and I cannot reproduce (or I don't get exactly what is the issue).

This is what I have tried:

GLSTestInsertArgumentReference.mp4

Can you give me a minimal tool wrapper or param definition that behaves like this?
