Re: [HACKERS] assorted code cleanup

The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       tested, passed
Spec compliant:           tested, passed
Documentation:            tested, passed

I've reviewed the code changes, and it's pretty clear to me that they clean things up a bit while not changing any
behavior. They simplify things in a way that make the code more comprehensible.  I've run all the tests and they behave
thesame way as they did before the patch.  I also trying manually playing around the the function in question,
`metaphone`,and it seems to behave the same as before.
 

I think it's ready to commit!

The new status of this patch is: Ready for Committer
