[gentoo-dev] gentoo completion update...

[Zach Forrest]

I corrected the "--usepkg" option.

Also, the "epurge" function I mentioned last time now lists any package
dependencies on the one you wish to remove (unless another version of 
the package exists), when the "--pretend" option is passed. One current 
limitation is that dependencies are not calculated on the specific 
versions themselves.
