Thanks for the vote of confidence, Ron.  The file 'suftab' is used
for hyphenation.  I would not hack through the PDP-11 code to figure
out how the original roff hyphenated, so I left hyphenation out.
Maybe I should have just borrowed nroff's algorithm?

Periods are padded with two spaces only if they stand at the end of
input lines.  This is so you can type

	Have you seen my wife, Mr. Jones?

without getting

	Have you seen my wife, Mr.  Jones?

If that doesn't cover your observed errors, it's a live bug.  Let me know.
