Bug#273406: update-alternatives: list all alternatives

[Dan Jacobson <jidanni@jidanni.org>]

Package: dpkg
Version: 1.10.22
Severity: wishlist
File: /usr/sbin/update-alternatives

There is no way to list all the alternatives, other than choosing
-all, which then asks on each one.

E.g., the user wants to check all the alternatives names with "pdf" in
them before picking one to call update-alternatives one.

Bad example, as there are none, but you get the idea.

Perhaps the best way to learn all the alternatives categories is just
$ ls /etc/alternatives
But in any case the man page should mention the best way.
