* We must interpret the quotes in the command line to rebuild the argv
* array correctly:
* - arguments are separated by spaces or tabs
* - quotes serve as optional argument delimiters
* '"a b"' -> 'a b'
* - escaped quotes must be converted back to '"'
* '\"' -> '"'
* - an odd number of '\'s followed by '"' correspond to half that number
* of '\' followed by a '"' (extension of the above)
* '\\\"' -> '\"'
* '\\\\\"' -> '\\"'
* - an even number of '\'s followed by a '"' correspond to half that number
* of '\', plus a regular quote serving as an argument delimiter (which
* means it does not appear in the result)
* 'a\\"b c"' -> 'a\b c'
* 'a\\\\"b c"' -> 'a\\b c'
* - '\' that are not followed by a '"' are copied literally
* 'a\b' -> 'a\b'
* 'a\\b' -> 'a\\b'
*
* Note:
* '\t' == 0x0009
* ' ' == 0x0020
* '"' == 0x0022
