spam.2434.eml:  SMTP mail, ASCII text
spam.2444.eml:  SMTP mail, ASCII text
spam.2454.eml:  SMTP mail, ASCII text, with very long lines (327)
spam.24583.eml: SMTP mail, ASCII text
spam.24595.eml: SMTP mail, ISO-8859 text, with very long lines (1861)

The man page should mention if 1861 refers to
A. That there are 1861 long lines in the file, or
B. that the longest line is 1861 octets long.

(Answer: B)

I tried to report it upstream, but it turned out to be a big hassle.

Also mention what the definition of a long line is, and if it can be
modified from the command line.
