 *  scanning at str and stores state in |sp|.  Subsequent calls
 *  should have |str| NULL so that the state stored in |sp| is used.
 *
 *  Spaces are incorporated into words with double quote characters only. 
 *  To incorporate a " char in a quoted word, use two:
 *  		" wibble""wobble"  ->  [SPC]wibble"wobble
 *  Quote chars inside words *not* started with a quotes are ordinary 
 *  characters.
 *
 *  <string> ::= { <space> <word> } <space>.

 *  <word> ::= " { <space-char> | <ord-char> | "" } "
 *          |  <ord-char> { <ord-char> | " }.
 *
 *  <space-char> is space, tab, newline etc.  
 *  <ord-char> is anything not a <space-char> or ".
