TinyMCE paste includes style color

[Ipstenu]

When I copy and paste from a webpage, it puts in the colors. This sounds like it's fine, but it does it even if no color is specified in the html. So if I copy from a 'normal' page where CSS sets the color to black, I get this:

<p style="color: #000000;">....</p>

That causes unexpected results with regards to my theme design (like breaking blockquotes).

I tested on 3.9 and trunk, and then at ​http://www.tinymce.com/tryit/basic.php

On tinyMCE.com it does not force insert the color. This did not happen on 3.8.x
