Wouldn't that be the text justification (pretty printing) going nuts
because of the format of this message? (long lines with no blanks)

This brings back memories of a similar problem I had in the early days
of IMP 3.0... can't recall how I fixed it though :-(
Isn't there a setting somewhere to limit the lenght of the lines that
will be text justified?
