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