subdir naming policy

[Brad Ely <elyb328_(_at_)_apk_(_dot_)_net>]

The following is the only case in the ports tree (excluding
infrastructure) where there is a collision on a subdirectory name:

chinese/hc    Port: zh-hc-3.0
math/hc       Port: hc-1.1

Is this (or should this be) against policy?

I'm asking because I've been using a symlinked 'ports/All' directory
for a while now without problem - except for the above case.
