I've run into a situation where the SUMMARY view of a logbook will extend
beyond the righthand border, thus requiring the user to scroll right.  This
does not occur in FULL or THREAD mode.  Long lines in the TEXT attribute
appear to be "pushing" the display too far to the right.  Limiting the
number of displayed summary lines works unless the first line is too long.

A temporary fix for this is to set summary lines = 0
