-  compressed files.  The new LESSOPEN/LESSCLOSE feature now provides
-  this functionality in a different way.
-
-* Some previous unofficial versions of less provided a -Z flag to 
-  set the number of lines of text to retain between full screen scrolls.

-  only in the E command.)
-
-* New command ":ta" is equivalent to "-t".

-* New command "s" is equivalent to "-l".
-
-* The - command may be followed by "+X" to revert to the default
-  for option X, or "-X" to get the opposite of the default.
