Autosave Interval has a very wide textfield entry

If you look at the attached screenshot you can see that the Autosave Interval textfield is 50 characters wide. This makes no sense for a value that is expressed in milliseconds.

The solution is to change the line 52 in draft/draft.module to:

'#size' => 6,

and on line 292 in draft/draft.module add the same:

'#size' => 6,

And that is perfect. Otherwise certain themes (like Burnt) have defects with other items (like theme selection checkboxes not being visible).
