Re: [RFC] Implement -list-thread-groups.

If others are fine with this too, then so am I. But I don't think
this is the normal procedure: For non-MI changes, my understanding
is that you're supposed to wait for approval unless the changes
are obvious (particularly for patches labeled RFC). I don't blame
you for doing this, given the poor track record we're having in
terms of speed of review - I guess we need more help.

Anyway, onto the patch...

Overall, looks good to me. Just a couple of minor nits and a question.

Can you add a comment for the new parameter in the function documentation,
please?

You're adding some spaces in what would otherwise be an empty line.
Can you get rid of that change?

This has little to do with your change, but I'm curious. What does
this code do? It seems to be adding a current-thread-id field in
the output, but why only doing it when requested_thread (and pid)
is -1?
