[O] adding "wrap=off" option to textarea for HTML export

[Eric S Fraga]

Hi,

I'm preparing some documentation, exported to HTML, that includes the
output of a src block.  Because this output is rather long, I have

#+attr_html: :textarea t :height 20

before the results of the src block.  This generates the correct
<textarea> form in the HTML output.  The text area form's width is
automatically set to the text width using CSS.  The problem is that some
of the output lines in the src block results are quite long and they
wrap; this looks ugly.

To turn wrapping off, I would need to add 'wrap="off"' to the textarea
form as this option cannot be controlled using CSS unfortunately.  I
don't see any way to do this from org.

Any suggestions on how to accomplish this, assuming it is possible?  

Many thanks,
eric
