Fix segfault in 1994/schnitzi - use fgets()

An example file that would cause the entry to crash is the Makefile. Now
it won't crash. Strangely without increasing the buffer size but even
using fgets() the Makefile did crash the entry. Changing the buffer size
is not a problem but whether or not some other larger file will cause a
problem or not I do not know. I don't see how it would but I don't see
how this happened either.

+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed the entry to not
+overflow the buffer (and segfault) by changing the call of `gets()` to
+`fgets()`. He also increased the buffer size. Prior to this fix one could not
+redirect the Makefile into this program, as an example problem. Thank you Cody
+for your assistance!
