  Modified files:
    bin/expr             expr.1 expr.y 
  Log:
  Make expr POSIX-compliant, and fix some bugs.  Specifically:
  
  - expr must conform to the Utility Syntax Guidelines, so use
  getopt() to eat the (non-existent) options.
  
  - Use the Standard type intmax_t for arithmetic.
  
  - If an argument cannot be *completely* converted to an integer, then
  it is a string.
  
  Additionally make some style cleanups near the modified lines.  This
  utility is still not completely style-compliant.
