Calling "option" before triggering show of datepicker causes datepicker to open

When calling the "option" method on a datepicker input before the user has focused on the corresponding input field, the calendar will appear.

Steps to reproduce:

1. Attach datepicker to an input element.

$("input").datepicker();

2. Set an option on the datepicker.

$("input").datepicker("option", "minDate", new Date( 2009, 8, 31 ) );

3. Load the page in any browser.

Expected Result: Datepicker will appear only once I click on the input field.

Actual Result: Datepicker appears immediately after the call to the option function.
