I put it back to show in non-verbose mode; after all it's only in the
infrequent case that it's set to anything at all, and also it doesn't
take up another column, as is the case with per-column stats targets.

I changed the separator from comma to semicolon, because it seems a
little less ambiguous. It's easy to change if people hate that.

... and pushed. Thanks.
