[PATCH 3/5] lei q: put keywords on one line in --pretty output

[Eric Wong <e@80x24.org>]

Don't waste precious terminal space when there are only a small
number of possible keywords supported/reserved for JMAP.  In the
future, we may implement more sophisticated wrapping for labels,
but it we'll cross tha bridge when we come to it.
