  60  * We must interpret the quotes in the command line to rebuild the argv
  61  * array correctly:
  62  * - arguments are separated by spaces or tabs
  63  * - quotes serve as optional argument delimiters
  64  *   '"a b"'   -> 'a b'
  65  * - escaped quotes must be converted back to '"'
  66  *   '\"'      -> '"'
  67  * - an odd number of '\'s followed by '"' correspond to half that number
  68  *   of '\' followed by a '"' (extension of the above)
  69  *   '\\\"'    -> '\"'
  70  *   '\\\\\"'  -> '\\"'
  71  * - an even number of '\'s followed by a '"' correspond to half that number
  72  *   of '\', plus a regular quote serving as an argument delimiter (which
  73  *   means it does not appear in the result)
  74  *   'a\\"b c"'   -> 'a\b c'
  75  *   'a\\\\"b c"' -> 'a\\b c'
  76  * - '\' that are not followed by a '"' are copied literally
  77  *   'a\b'     -> 'a\b'
  78  *   'a\\b'    -> 'a\\b'
  79  *
  80  * Note:
  81  * '\t' == 0x0009
  82  * ' '  == 0x0020
  83  * '"'  == 0x0022
  84  * '\\' == 0x005c
