One bug fix, and some changes to the --interactive output format

I messed up merging the Squawk display in interactive mode into my
master.

However, the original source posted by terribl causes a print line
length greater than 80 characters. This in turn causes the lines to
spill over on a terminal display. I have therefore re-formatted some of
the output so that it fits within 80 characters.
