Comment 8 for bug 98371

To be really clear, Tres said that it's not desirable to strip lines from user input, with that I fully agree.

Consider the following two text areas

<textarea>foo</textarea>

<textarea>
foo</textarea>

In both examples above, the user input is 'foo', no new lines. So we wouldn't be stripping anything from the user input. If anything, at the moment testbrowser is adding new lines to the user input, which it really shouldn't be doing.
