The sums are computed as described in RFC 1321. When checking, the
input should be a former output of this program. The default mode is
to print a line with checksum, a character indicating type (`*' for
binary, ` ' for text), and name for each FILE.[/quote]

two characters, often both spaces, between the two stringsets.
I don't think the algorithm works correctly with only one space between the stringsets.
