Let's get rid of |number()|, |set_number()|, |extension()|, and
|set_extension()| while we're in here.  They're not helpful.

I'm confused by this comment.  What further work is needed?  I would have
thought this could take |locale_| into account and only use the prefix/suffix
logic if we're dealing with "US".  No?

[GeorgeY, 2011/05/20 00:41:49]

Not only, some other countries support the splitting of the 7 digits number into
3-4 parts (Russia, for example), though I *never* saw any non-US form doing it.
