Yeah, that's the real problem - one doesn't get the same warnings
everywhere. Still, I think we should consider applying the portion of
the proposed patch that avoid relying on the contents of the fgets()
buffer after fgets() returns NULL, because at least on MacOS the man
page for gets/fgets says:
If an error occurs, they return NULL and the buffer contents are indetermin=
ate.
Indeterminate is bad. The actual chance of a crash seems low, and I
notice that the Linux man page has no such caveat, but still.
