At this point in the completion, "-g" is an ignored prefix of the
"-g+" completion, which means it is part of the word to be completed
but should not be shown in the list of matches.  So it isn't.

The listing doesn't change on subsequent TABs because the fact that -g
is a possible completion makes -groupsize ambiguous.  You have to do
something to disambiguate, e.g., type a number (of octets) or an "r"
before pressing TAB.

We had a brief discussion a few weeks ago of supplying a set of default
zstyles, I've been gradually building up a suggested list.  Both of
these were the first things on it:

}   zstyle ':completion:*:descriptions' format '%B%d%b'
}   zstyle ':completion:*' group-name ''
}

} What subsequent tab presses does, depends a lot on your configuration.

In this case it doesn't, really; because one of the groups is empty,
there's not much else that can happen, e.g., menu completion has no
alternatives to cycle through.
