Update to Steve Greenberg's fine LBR directory program.  Simplified
display.  Excellent for use as a LDIR.COM both for standard alone and
for automatic use with LUX77B.  Shows contents of a .LBR, length both
in records and 'k', tells whether normal, squeezed or crunched and if
either of those, the original name.  This version checks for presence
of BYE5.
