Add tests for trim on CSV

Hi There,

I just noticed that the trim option in views didn't really seem to be having an effect on the output. Beginning on line 152 of views_data_export.theme.inc, it looks like it is checking to see whether the option is set in the view and then calls trim if appropriate.

      if (!empty($vars['options']['trim'])) {
        $output = trim($output);
      }

But setting or not setting the option has no effect.

But if I just change line 151 to trim everything:

      $output = trim(decode_entities(strip_tags($value))); // RRCJAB added trim

then it works beautifully (but obviously on all fields instead of just selected ones).

So maybe this is a bug in views? Honestly, I don't know, but I figured I should mention it.

thanks,
John
