If end or start is null is infinite

[adrianoresende]

When I use this code:

:disabled-dates="[{ start: new Date(), end: null }]"

Why this code should not disable days today until infinity?

OBS:
:disabled-dates="[{ start: null, end: new Date() }]" is same result, this is wrong.
This should disable the days until today and available in future.

Thanks. I hadn't initially considered using null as an 'endless' date, but I don't see an objection with it.
