Sounds good.

Well, yes, but I've run into a snag in the very clear instructions. If
someone installs less and they don't have envar EDITOR set, they will be
told '/usr/bin/editor: command not found' or something similar. This is
not clean behaviour. Users will look for an "editor" package,
especially since none of the editors provide /usr/bin/editor yet. There
is nothing in the dependencies of less that prevents this from
happening, hence this bug.

But this isn't what the policy says. It says:

That's not what I read the policy manual to say. If there was a
sentence added to the paragraph above that said:
"/usr/bin/sensible-{editor,pager} may be used as well if the developer
(packager?) wishes."
Since it's not hard at all for less to use envar EDITOR (it comes that
way), I can't use /usr/bin/sensible-editor. Maybe I'm being too
nitpicky.
/usr/bin/sensible-editor works better since if envar EDITOR isn't set
and /usr/bin/editor hasn't been set with update-alternatives,
sensible-editor then tries ae(1) and vi(1). If neither of -those- work,
it then says "Couldn't find an editor!\n" "Set the $EDITOR environment
variable to your desired editor."
This is an acceptable error message.
