newlines removed and rewritten.

If I enter the following code into the editor in view source mode:

<pre>
blah
blah
blah
blah
blah
blah
</pre>

If I then exit view source mode then return to view source mode the code is rewritten to:

<pre>blah<br />blah<br />blah<br />blah<br />blah<br />blah</pre>

My users will be pasting blocks of source code (not html) into the window and I would like the source code to look in source mode as it did when it was entered.

Is it possible to make FCK editor leave the code inside of a pre block alone or to leave whitespace alone? I didn't find anything in the docs or on google.

Any ideas? Thanks.
