remove unneeded justify_format() call from do_justify() which caused

problems if the original paragraph was one line long and ended with a
tab or tabs; unjustification would restore the justify_format()ted line
instead of the original line

+	  do_justify_void() and do_full_justify(). (DLR)
 	- Modify the justification algorithm to work the same way as in
 	  the current version of Pico, i.e, add a space at the end of
 	  each line of the justified paragraph except for the last one,
 	  and if there was a space at the end of the last one, remove
-	  it.  Changes to justify_format() and do_justify().  (Note that
-	  the addition of spaces to justified lines means that
-	  first_mod_line can no longer be used to reliably detect the
-	  first modified line in a paragraph, since a line unmodified by
-	  justify_format() may get a space tacked onto the end of it
