Yeah, since it looks like it would require a "force push" with an amended
message (which github strongly discourages because it screws up people who've
cloned the repo), I'm not going to do that.  

But for what it's worth, I will change it in the changelog that gets
mailed out in the crash-7.2.2 ANNOUNCE message on this mailing list,
and it will also will be seen in the updated version of 
http://people.redhat.com/anderson/crash.changelog.html.
