What about the token side of things? <program-name> and <process-id>?
For my use case, its important that I can do something like that too.

I didn't add a new way to quote (not that any way existed before), just
a substitute argument delimiter using '|'. It's difficult to get double
quotes and spaces into env. vars, so I worked around that
difficulty in what I think is a sensible way.

Great, but what about <program-name> and <process-id>, that is the substantial
part of the patch. I can't hook up QtCreator with the fixed arguments that are
added currently, QtCreator doesn't care for the program-name and only works if
presented with <-debug process-id>
