-  Explaination:
-  (?!\s*$)                            # Don't match empty last value.
-  \s*                                 # Strip whitespace before value.
-  (?:                                 # Group for value alternatives.
-  '([^'\\]*(?:\\[\S\s][^'\\]*)*)'     # Either $1: Single quoted string,
-  | "([^"\\]*(?:\\[\S\s][^"\\]*)*)"   # or $2: Double quoted string,
-  | ([^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)  # or $3: Non-comma, non-quote stuff.
-  )                                   # End group of value alternatives.
-  \s*                                 # Strip whitespace after value.
-  (?:,|$)                             # Field ends on comma or EOS.
-
-  For practical reason, we remove the case with single quoted string.
