File: /usr/sbin/update-alternatives
I would like to see a --list-all option added to update-alternatives.
The semantics should be obvious: list all valid arguments to, say,
update-alternatives --config $i.
I have attached a patch which (AFAICT) DTRT.
I have no experience writing documentation, man pages in particular,
but feel free to use the following text as inspiration:
--list-all
Display all link groups, sorted alphabetically.
