53 * We must interpret the quotes in the command line to rebuild the argv
54 * array correctly:
55 * - arguments are separated by spaces or tabs
56 * - quotes serve as optional argument delimiters
57 * '"a b"' -> 'a b'
58 * - escaped quotes must be converted back to '"'
59 * '\"' -> '"'
60 * - an odd number of '\'s followed by '"' correspond to half that number
61 * of '\' followed by a '"' (extension of the above)
62 * '\\\"' -> '\"'
63 * '\\\\\"' -> '\\"'
64 * - an even number of '\'s followed by a '"' correspond to half that number
65 * of '\', plus a regular quote serving as an argument delimiter (which
66 * means it does not appear in the result)
67 * 'a\\"b c"' -> 'a\b c'
68 * 'a\\\\"b c"' -> 'a\\b c'
69 * - '\' that are not followed by a '"' are copied literally
70 * 'a\b' -> 'a\b'
71 * 'a\\b' -> 'a\\b'
72 *
73 * Note:
74 * '\t' == 0x0009
75 * ' ' == 0x0020
76 * '"' == 0x0022
77 * '\\' == 0x005c
