Comment (by cal@…):

 Looks good at first sight – unfortunately I can't test right now because
 my working copy is busy tracking other changes and I don't want to risk
 mix them (why don't we use git again? :/).

 One thing I noticed is that your changes put `set group [lindex $portlist
 0]` before the length check of `$portlist`. Since `lindex` doesn't fail on
 invalid indices that's not a problem per-se, I just think it would be a
 little cleaner to move it after the check.
 The indentation seems to be a little off in some places, too, but that's
 just a cosmetic issue.

 Everything else seems to be in order – what's the problem with testing it?
 Don't have any select-capable ports installed? You can just install
 `python_select` or `mysql_select` – they won't have anything to select,
 but they should still show up just fine in your summary output.
