  56  *
  57  * We must interpret the quotes in the command line to rebuild the argv
  58  * array correctly:
  59  * - arguments are separated by spaces or tabs
  60  * - quotes serve as optional argument delimiters
  61  *   '"a b"'   -> 'a b'
  62  * - escaped quotes must be converted back to '"'
  63  *   '\"'      -> '"'
  64  * - an odd number of '\'s followed by '"' correspond to half that number
  65  *   of '\' followed by a '"' (extension of the above)
  66  *   '\\\"'    -> '\"'
  67  *   '\\\\\"'  -> '\\"'
  68  * - an even number of '\'s followed by a '"' correspond to half that number
  69  *   of '\', plus a regular quote serving as an argument delimiter (which
  70  *   means it does not appear in the result)
  71  *   'a\\"b c"'   -> 'a\b c'
  72  *   'a\\\\"b c"' -> 'a\\b c'
  73  * - '\' that are not followed by a '"' are copied literally
  74  *   'a\b'     -> 'a\b'
  75  *   'a\\b'    -> 'a\\b'
  76  *
  77  * Note:
  78  * '\t' == 0x0009
  79  * ' '  == 0x0020
  80  * '"'  == 0x0022
  81  * '\\' == 0x005c
