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.
