More about 2011/richards and macOS

This includes a minor code change. I believe at this point that it's an
inherent issue of macOS but I might be wrong. I'll certainly look at
this more in the future but I'm going to try and work on the remaining
README.md files first. Time will tell how much I succeed.

+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed a minor problem
+that showed up in both linux and macOS. He notes however that as of this time
+this entry does not work with macOS. See [bugs.md](/bugs.md) for more details.
+Thank you Cody!

 ## Try:
 
 ```sh
 echo '10 9 8 7 6 5 4 3 2 1*p*p*p*p*p*p*p*p*p' | ./richards
 ```
