50  * CommandLineToArgvW            [SHELL32.@]
51  *
52  * We must interpret the quotes in the command line to rebuild the argv
53  * array correctly:
54  * - arguments are separated by spaces or tabs
55  * - quotes serve as optional argument delimiters
56  *   '"a b"'   -> 'a b'
57  * - escaped quotes must be converted back to '"'
58  *   '\"'      -> '"'
59  * - consecutive backslashes preceding a quote see their number halved with
60  *   the remainder escaping the quote:
61  *   2n   backslashes + quote -> n backslashes + quote as an argument delimiter
62  *   2n+1 backslashes + quote -> n backslashes + literal quote
63  * - backslashes that are not followed by a quote are copied literally:
64  *   'a\b'     -> 'a\b'
65  *   'a\\b'    -> 'a\\b'
66  * - in quoted strings, consecutive quotes see their number divided by three
67  *   with the remainder modulo 3 deciding whether to close the string or not.
68  *   Note that the opening quote must be counted in the consecutive quotes,
69  *   that's the (1+) below:
70  *   (1+) 3n   quotes -> n quotes
71  *   (1+) 3n+1 quotes -> n quotes plus closes the quoted string
72  *   (1+) 3n+2 quotes -> n+1 quotes plus closes the quoted string
73  * - in unquoted strings, the first quote opens the quoted string and the
74  *   remaining consecutive quotes follow the above rule.
