Actually, that's not good wording.  It implies that NUL and delimiter
characters are treated in the same way, but they aren't.

    -N nchars  return only after storing exactly NCHARS characters, unless
               EOF is encountered or read times out, ignoring any NULs, and
               not stopping for delimiters
