Wrap output in pretty-print unless failure, then show verbose

[alerque]

(Post RIIR #98)

Output is either too verbose or too quiet depending on how things worked out.

We should be able wo capture and wrap output on a per-target basis, show what steps are being run, bun hide output except in the event of a failure.
