spurious span tags when copy+paste onto

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open a tinymce editor window
2. Select some html from a different part of the notebook, not inside a 
tinyMCE, but directly on the output
3. Drag that text onto the tinymce editor window

What is the expected output? 
The html should be copied+pasted literally.

What do you see instead?
An spurious <span id="cell_outer_58"> content_here </span> appears wrapping the 
html. This tags will mess up with the notebook later.

What version of the product are you using? 
4.7.1

On what operating system?
ubuntu 10.04, using the binaries from the website, I think.

I don't think we can fix the pasting.  You are selecting the span tag too, so 
it gets copied too.  This means that two tags with the same id will be in the 
document---not good.

As a workaround, click the paste button with a "T", which will let you paste in 
plain text, rather than html.

Actually, it looks like we can set some options when pasting to, for example, 
strip out spans, or do some processing to strip out id numbers.  So this looks 
doable after all.  See http://www.tinymce.com/wiki.php/Plugin:paste
