[PATCH 3/6] Unthreaded mode: allow different result format

It is likely that the user will want a different line format for
unthreaded mode from tree mode; in particular the thread structure
graphics are unnecessary in unthreaded mode.

Add a new customisable variable and set it to something sensible.
