+
+ Remove dependencies on getline and getdelim.
+ Also, remove update-game-scores's limits on game scores and
+ simplify its file-locking code.
+ * update-game-score.c (struct score_entry): Unify the username and
+ data members to a single user_data member, since they don't need to be
+ changed independently and getdelim and getline aren't helpful.
+ Make the score member char *, not intmax_t, so that scores are not
+ limited to intmax_t. All uses changed.
+ (lose_syserr): A zero errno stands for invalid data in score file.
+ (normalize_integer): New function.
+ (main): Use it. Check for invalid scores. Omit redundant stat check.
+ (read_score): First arg is now a string, not a FILE *. All uses
+ changed. Do not use getdelim or getline; that's way simpler.
+ (read_scores): Read the whole file, and let read_score handle each
+ line.
+ (score_compare): Compare strings representing integers, not integers.
+ (write_scores) [DOS_NT]: Eliminate unnecessary chmod.
+ (lock_file): Simplify locking code, eliminating goto.
+ Check for unlink failure.
