In glob0() the iterator is used to walk over an array of Char's. Char is
defined as uint_fast64_t (64 bits) while the iterator is type int (32 bits).
The side effect of this type conversion is the high bits which were used to
indicate if a special character was a literal or special were dropped. As a
result, all special character were treated as special, even if they were
supposed to be literals.
