| Here is another, more subtle bug.  fgets will write up to BUFSIZ characters
| (in this call) to line.  This is not including the final '\0' character.
| The best thing to do is declare char line[BUFSIZ + 1], and all will be well.
+---------------

fgets writes BUFSIZ-1 characters in all Unix and Unix-like systems I have
encountered, specifically to leave room for the trailing \0.  RTFM.
