Try re-running the commands with COLUMNS=0, I thiiink that's the magic
incantation to un-break the logs.
And for the record this is why I think truncating lines in Guile traces
is a very terrible idea.  It usually hides a lot of important info and
makes it necessary to re-run expensive computations for no reason.
