bug#10909: 24.0.94; doc of `define-minor-mode'

["Drew Adams" <drew.adams@oracle.com>]

The doc says that the mode function that gets defined accepts an
optional argument.  The interactive description is OK.
 
The non-interactive description says only "When called from Lisp, it
enables the mode if the argument is omitted or nil, and toggles the mode
if the argument is `toggle'."
 
IOW, it says nothing about what happens when an arg is passed that is
not nil or omitted or `toggle'.  And I've seen at least one user try to
use `(foo-mode t)'.  It turns out that that has the same effect as
`(foo-mode 1)', but nothing in the doc says that it should.
 
The doc should, at a minimum, say what kinds of non-nil arguments it
expects (e.g. integer).
 
Personally, I think it should probably go beyond that and say also what
it does with other non-nil args, but that's your call.
