Can you explain why wordexp.c on the referenced site has a completely different (and older) copyright? Did they merge in another implementation?

I'm guessing that the linked implementation probably hadn't been touched since 2008. My comment that this was source code from 2011 was referring to the fact that this release of libc (Libc-763.11) is from 2011.
