Make usage of 1998/dloweneil more inclusive

This is a cosmetic change only and rather unimportant but I have to be
complete: when I added the alt code I used the word anticlockwise (as I
would) instead of counterclockwise. But since the original entry
referred only to counterclockwise I decided to make it use both like the
alt code does.

 ## Alternate code:
 
 This version has it so that where in addition to `a` moving you
-anticlockwise/counterclockwise `h` does as well; and in addition to `s` moving
+counterclockwise/anticlockwise `h` does as well; and in addition to `s` moving
 clockwise `l` does as well. Instead of using `d` to drop the letter you can do
 `j` or space. Finally to quit this version you can press `q`.
