The space is supposed to be there because ends the scanning for a filename  
for \openin. If not present, \openin will expand \ifeof\@inputcheck to  
finish scanning for the filename. The LaTeX kernel is identical in this  

The bug is elsewhere as I described earlier but that message probably  
didn't get to your part of the world yet... :-)
