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	* - an odd number of '\'s followed by '"' correspond to half that number
59	* of '\' followed by a '"' (extension of the above)
60	* '\\\"' -> '\"'
61	* '\\\\\"' -> '\\"'
62	* - an even number of '\'s followed by a '"' correspond to half that number
63	* of '\', plus a regular quote serving as an argument delimiter (which
64	* means it does not appear in the result)
65	* 'a\\"b c"' -> 'a\b c'
66	* 'a\\\\"b c"' -> 'a\\b c'
67	* - '\' that are not followed by a '"' are copied literally
68	* 'a\b' -> 'a\b'
69	* 'a\\b' -> 'a\\b'
