  33  *
  34  * We must interpret the quotes in the command line to rebuild the argv
  35  * array correctly:
  36  * - arguments are separated by spaces or tabs
  37  * - quotes serve as optional argument delimiters
  38  *   '"a b"'   -> 'a b'
  39  * - escaped quotes must be converted back to '"'
  40  *   '\"'      -> '"'
  41  * - an odd number of '\'s followed by '"' correspond to half that number
  42  *   of '\' followed by a '"' (extension of the above)
  43  *   '\\\"'    -> '\"'
  44  *   '\\\\\"'  -> '\\"'
  45  * - an even number of '\'s followed by a '"' correspond to half that number
  46  *   of '\', plus a regular quote serving as an argument delimiter (which
  47  *   means it does not appear in the result)
  48  *   'a\\"b c"'   -> 'a\b c'
  49  *   'a\\\\"b c"' -> 'a\\b c'
  50  * - '\' that are not followed by a '"' are copied literally
  51  *   'a\b'     -> 'a\b'
  52  *   'a\\b'    -> 'a\\b'
  53  *
  54  * Note:
  55  * '\t' == 0x0009
  56  * ' '  == 0x0020
  57  * '"'  == 0x0022
  58  * '\\' == 0x005c
