Z:englobe-dpkg-man--f9154e-Remove an alternative and all/en

Remove an alternative and all of its associated slave links. I is a name in the alternatives directory, and I is an absolute filename to which I could be linked. If I is indeed linked to I, I will be updated to point to another appropriate alternative, or removed if there is no such alternative left. Associated slave links will be updated or removed, correspondingly. If the link is not currently pointing to I, no links are changed; only the information about the alternative is removed.
