Summary: Pasting rich text into a new TextEdit document isn't fully undone when invoking Undo.

Steps to Reproduce:
1. Open a new TextEdit document.
2. Copy some rich text from a webpage with obviously styled text, such as http://eggfreckles.net/notes/listening-to-less-music/, from Safari
3. Paste that text into TextEdit.
4. Undo (Edit->Undo or Command-Z).
5. Type new text.

Expected Results:
The new text will be in the default text style of the document.

Actual Results:
The new text picks up the style of the pasted-and-undone text.

Regression:
I've tested in Snow Leopard 10.6.8/10K549, and this bug exists there as well.

Notes:
I haven't tested copying text from sources other than Safari.

The egg freckles link in the original bug is a 404 now. Try something from the main page: http://eggfreckles.net
