See my other patch for the -Sw case. I seem to have a tendency to
overlook the RET_ERR ones though...

Ok, good point, I didn't notice that. In that case I think we should
move this back to where it was originally, but make sure only packages
for the current repo get unset. This might be a good time to introduce a
pmpkg_t parameter to the download callback as well.

I agree, but I don't mind either way. Since PM_ERR_PKG_INVALID_NAME is
checked in the commit I'm not sure we even need the pre-computation any
more. I'll have a closer look when I get the chance.
