-	Given a pointer to a string, parse the string extracting fields

-	In order to provide a working buffer for extracting arguments into,
-	with appropriate stripping of quotes and translation of backslash
-	sequences, we allocate a working buffer at least as long as the input
-	string.  This ensures that we always have enough space in which to
-	work, since the extracted arg is never larger than the input string.
