  The reason that ``cat xyz*'' is expanded and ``cat <xyz*''
is not has to do with the C getchar() call.  cat takes any
arguments on the command line that don't start with a ``-'',
expands them, and interprets them as filenames.  However, if
you use the ``<'' before the filename, the filename is actually
used as stdin and the filename is not put on the command line.
Therefore, cat thinks that you are typing in somthing from the
terminal.  Hope this helps.
