If we skip the second case, and the package has some files in file/dir, then
this is going to be weird :)
But what I don't get is why doesn't it totally fail in both cases ?
Shouldn't there be a conflict between a regular file and a directory ?
It looks like this isn't the case currently. Apparently, as long as there is
a directory on one side, conflict check are skipped. So there might be a
reason for that, I'm not sure..

I think it's rather between a symlink to a directory and a directory that we
can choose between skipping and extracting, but I could be wrong.
