- as requested by ESR, remove the use of parentheses from the usage
summary, it confused some man page conversion tool he has
- updated documentation for the -p option to mention the word "role"
so anyone search for role in the man page will still find it
- removed use of .UC, it is listed as deprecated in all the current man
documentation I could find, when it was even documented at all
- other minor spelling and formatting (hyphenation) changes
- various commands were missing from various help files
- fix a few inconsistencies between similar help files
- M-2 doesn't do #twoweapon when number_pad is enabled
- M-? usually displays #? help info
- weasel-word the reason the screen shown in the Guidebook looks little like
several windowports
- document the playersuffix syntax in the nethack.6 man page
