Well, you buy less dependency with more airtime (well, ether time).
Still, I wouldn't object as an editor is one of the basic tools
that you need early when configuring a new system...

But I wonder how difficult it to would be to support a multitude of
EXTRACT_SUFXes, being chosen by a preference in mk.conf or maybe by 
extraction tools already being installed in the build environment.
