RE: Also allow -list-thread-groups (--available) without a live selected thread

Hi,

I had a quick look at the patch and I wanted to mention
that the parentheses are kind of weird.  Don't get me wrong,
they do work, but there is some weird and unnecessary groupings
of conditions, if that matters.

Thanks for the patch though, I will use it.

Marc
