[general] change to `list' in crabs

david (10/14/82)

Some minor changes have been made to crabs.  When you
ask for a list (l or list) you will now be asked if
you want the output on the line printer, on your terminal
or into a file.  If you want it on the line printer as
before, just type `l'.  If the output is printed on your
terminal or into a file, the lines will be shorter, so that
they fit on the screen.  The output file will be called
list.out, so make sure you don't already have a file of that
name that you want to keep.
