Odd help for -Wall

I suspect the following is an error in the help message:

$ nvc --help=switch | grep Wall
-Wall Commands

Thanks for the comment Paul and yes, the help message should be cleaned-up so I added TPR #28862 and sent it our engineers.

Right now in 20.7, “-Wall” is just a place holder and non-functional, so the message printed should reflect this.
