Exacly the `ferror(F)` is false here. If it is false we may have successful
read or EOF after read. So the message about "Assuming that stream reaches
end-of-file here" is really an assumption here (pick one from the two possible
results). And if EOF happens and `ferror` is false the `feof` must be true,
this is revealed when we know that `ferror` is false.
