Not only (eof). Any reading beyond end of file causes this state to be
remembered in the character-look-ahead buffer of the I/O system, so that further
reading returns NIL.

But I think this was not the problem of the initial poster, where the low-level
read() did not return. The look-ahead happens on a higher level.
