- The scanf() family now always returns the number of assignments made
unless an error occured or an EOF was hit during conversion before the
first assignment could be made.

- strtok() did not terminate properly if the last token in the string
did not end with a separator character but with a '\0' byte. Fixed.

- The directory scanning functions opendir/closedir did not get the global
directory data tracking data structure initialized which later led to
Enforcer hits and maybe trashed memory. Fixed.
