Datepicker: Ability to position current month out of view with showCurrentAtPos option

[copesc]

Hi, I've made a small jsfiddle to clarify the issue:

​http://jsfiddle.net/Hsy5w/

If you go forward to january 2012, the first 2 months are undefined, when showCurrentAtPos is set as -2. If I set showCurrentAtPos: -1, the first month is undefined.

Changing to a feature request. I'm pretty sure showCurrentAtPost was never meant to be used with the current month out of view.

Updated test case: ​http://jsfiddle.net/Hsy5w/1/

I found a solution and patched the jquery-ui.js in basically two code lines in the datepicker subroutines _adjustDate() and _updateDatepicker() (see also cross-posting in ​http://bugs.jqueryui.com/ticket/9923#comment:4 ):
