Now that you point this out, I realize we can use "-gdb-set args" right now.
Not only that, but -gdb-show args does works while -exec-show-arguments
does not.

I prefer to use -gdb-set since I can.

You are right.  I had seen the N.A. and thought that just the example was not
available, not the whole command.
