update-alternatives: --all can be used to restore broken alternatives
Since alternatives are repaired every time they are reconfigured,
the user can use --all to reconfigure them all with the current choice
and repair everything. Document this in the manual pages and ensure
that it really works that way by returning a valid choice.
