54  * CommandLineToArgvW            [SHELL32.@]
55  *
56  * We must interpret the quotes in the command line to rebuild the argv
57  * array correctly:
58  * - arguments are separated by spaces or tabs
59  * - quotes serve as optional argument delimiters
60  *   '"a b"'   -> 'a b'
61  * - escaped quotes must be converted back to '"'
62  *   '\"'      -> '"'
63  * - consecutive backslashes preceding a quote see their number halved with
64  *   the remainder escaping the quote:
65  *   2n   backslashes + quote -> n backslashes + quote as an argument delimiter
66  *   2n+1 backslashes + quote -> n backslashes + literal quote
67  * - backslashes that are not followed by a quote are copied literally:
68  *   'a\b'     -> 'a\b'
69  *   'a\\b'    -> 'a\\b'
70  * - in quoted strings, consecutive quotes see their number divided by three
71  *   with the remainder modulo 3 deciding whether to close the string or not.
72  *   Note that the opening quote must be counted in the consecutive quotes,
73  *   that's the (1+) below:
74  *   (1+) 3n   quotes -> n quotes
75  *   (1+) 3n+1 quotes -> n quotes plus closes the quoted string
76  *   (1+) 3n+2 quotes -> n+1 quotes plus closes the quoted string
77  * - in unquoted strings, the first quote opens the quoted string and the
78  *   remaining consecutive quotes follow the above rule.
