Reword documentation for .width() method

[[email protected]…]

The wording on the page ​http://api.jquery.com/width/ is confusing.

This text:

The difference between .css(width) and .width() is that the latter returns a unit-less pixel value (for example, 400) while the former returns a value with units intact (for example, 400px).

could be beter written as:

The difference between .width() and .css(width) is that the former returns a unit-less pixel value (for example, 400) while the latter returns a value with units intact (for example, 400px).
