Yes, you're right. Sorry. And only now I see that qjackctl's jack port
list sorting is somewhat flawed, and has been like that for quite a long
time.

Nevertheless, I'm really glad you noticed and insisted on the matter, Fons.

In fact, even my suggestion of numbering ports like out_1L, out_1R, ...
doesn't come right either, as you've verified.

I though the correct sorted output should be:

  out_1L
  out_1R
  out_2L
  out_2R

but it actually comes like this:

  out_1L
  out_2L
  out_1R
  out_2R

so I think I gotta review the code, as it doesn't obey the "natural" order
I've mentioned earlier which I guess as being the consensual one to do.

I think you shouldn't bother on jack maintaining any guarantee on port
ordering, as clients might be quite dynamic in general, when regarding
port (de)registering.

Bye now. But I'll be back...
