OK. There are actually two changes: moving the insertion until after
e->name is set up (which has no functionality impact) and changing the
manner of insertion. I split them up to try to make them more readable,
but clearly you figured out what I was going for.

Actually, I removed it intentionally (though clearly I should have
documented it). It's casting from an unsigned int to an unsigned short.
Such a cast is at best pointless (since the compiler performs the exact
same cast implicitly -- see C99 6.5.2.2, paragraph 7), and at worst
masks an error (e.g., if the type of n is changed).
Is there some subtle issue I'm missing here?
