Hyphens, minus, and dashes in Debian man pages

As a side note. I want to say thank you to both rra and branden. A lot of conversations about fonts and layout can lead to ill-chosen words between participants, because even a slightly off font can cause the brain to think 'lion, get ready to fight'. This conversation had instead a lot of 'we agree', and 'we can agree to disagree', and also a LOT of documents I have not read. [I need to get a copy of the updated Kernighan troff manual to add to my Kernighan collection!]

Again thank you for teaching and making this conversation something enjoyable to read.
