So we have both invert and inverted attributes. Fun :-).
See sysfs-class-led and sysfs-class-led-trigger-oneshot.
We definitely want this documented. We probably want this for most
triggers, maybe it should get one implementation in library somewhere?
Otherwise it makes sense.

Accepting 42 as valid value sounds wrong. Anyway, this should do what
oneshot trigger does.
