It's not mishandled. It's handled exactly as I would have expected. If  
"blah-" and "blah" result in the same thing, then how do you know the  
difference?

Stripping any possible leading or trailing hyphens is much more efficient  
than checking every single word to see if it's empty.

However, if you have an instance of "--", your solution will remove the  
extra empty string, whereas mine does not. Not sure if that's important.
