The problem is, you can't use fgets if you allow NUL as a character,
because you can't check the length of such a string with strlen().  If
you want to write a NUL-safe fgets variant, that would be fine.  It
would need to return the number of bytes read in, and we'd have to use
memrchr() (more likely, write our own) instead of strrchr().

We can choose a non-NUL byte if that would help; perhaps 0x7f or 0x01.
