  59  *
  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  * - consecutive backslashes preceding a quote see their number halved with
  68  *   the remainder escaping the quote:
  69  *   2n   backslashes + quote -> n backslashes + quote as an argument delimiter
  70  *   2n+1 backslashes + quote -> n backslashes + literal quote
  71  * - backslashes that are not followed by a quote are copied literally:
  72  *   'a\b'     -> 'a\b'
  73  *   'a\\b'    -> 'a\\b'
  74  * - in quoted strings, consecutive quotes see their number divided by three
  75  *   with the remainder modulo 3 deciding whether to close the string or not.
  76  *   Note that the opening quote must be counted in the consecutive quotes,
  77  *   that's the (1+) below:
  78  *   (1+) 3n   quotes -> n quotes
  79  *   (1+) 3n+1 quotes -> n quotes plus closes the quoted string
  80  *   (1+) 3n+2 quotes -> n+1 quotes plus closes the quoted string
  81  * - in unquoted strings, the first quote opens the quoted string and the
  82  *   remaining consecutive quotes follow the above rule.
