It already is in ftdetect/macports.vim [1], except that it is only done
for the events BufNewFile,BufRead and not for BufWinEnter, while the
latter is the reason your line actually works. The filetype is
overridden each time again the buffer of a Portfile is displayed.
Although this works in most circumstances, it has side effects when
using hidden buffers.
