That's exactly what I have done.

I'm not sure that `proof by example' should be necessary. but here's an
example showing Totalview separate the two:

Totalview is probably the world's best C/C++ debugger (apart fron GDB, of

remove it.

As a maintainer I would try to accommodate such requests and reserve my
judgements for technical matters.
