Pull in COLUMNS environment variable and default it to 80.

(filter_mail): Instead of printing which folders have been added to,
print one line per saved non-spam message: its folder, message number,
and from and subject headers.  Use COLUMNS and hard-coded proportions
to determine how much of the line to allocate to each field printed.
