I don't really see much point to most of this commit. But I don't see much
reason *not* to do it either...  Basically all it does is:

- renames the function
- moves the definition to a different place in the source file (not sure why)
- avoids creating local variables in the caller.

So I'm pretty ambivalent. But I'll ACK it to avoid creating conflicts further in
the branch.
