Log:
  When man pages are formatted in UTF-8, .Fl is encoded as U+2212 "MINUS
  SIGN" instead of U+002D "HYPHEN-MINUS".  This is unfortunate for two
  reasons: 1) this is not the character which is actually used on the
  command line, and 2) it makes it impossible to search a man page for a
  specific command-line option.
  
  This patch fixes this, but there are other unresolved issues, such as
  confusion between -, \- and hy: while the latter is always (and only)
  used for hyphenation, both - and \- are used for negation and
  subtraction, and \- is used for command-line options and sometimes
  also for parenthesis.  IMHO, the correct Unicode characters are:
  
   - hyphenation: either U+2010 or U+00AD, most likely the former (the
     latter is the so-called soft hyphen, used to indicate a point at
     which a text processor is allowed to hyphenate a word)
  
   - negation and subtraction: U+2212
  
   - parenthesis: in English, U+2214, with spaces suppressed before and
     after; in some others (such as Norwegian), U+2213 with spaces
     retained.
  
   - command-line options: U+002D, because that is what is actually used
     on the command line.
  
  However, fixing this would require extensive modifications to (at least)
  the doc and man macro sets...
