Catchup with the times:

- Avoid use of word that Americans don't know how to spell
 - Avoid use of capital letters when referring to command names
 - Bookmarks do span files
 - Use .Qq where appropriate.  I didn't use .Sq or .Dq where `' and ``''
   appear, since it's not clear to me what modern usage of those two
   macros is.
 - Say simply: ``See .Xr xxx 1'' rather than ``See the .Xr xxx 1 command''.
   This former style has undoubtedly increased in popularity due to
   html and hyperlinks, but it's always been around (esp. for manpage
   sections other than section 1).
 - Use .St
 - Dedocument use of `-' to mean that `more` should read from its
   standard input.  The modern preferred way to read from standard
   input is by specifying /dev/stdin.  This is not a prelude to changing
   more's behaviour within the short term (ie. at least 3-4 years).
