coder + drush error when using 'no-empty'

This is actually only not reported on when running coder using drush. If you run it through the UI it works perfectly.

If you run coder reviews using the drush command line method and are providing it with the 'no-empty' option, then if there is only one error reported in the module, it won't be displayed. For example, if you run it on the invite module like this:

drush coder minor i18n no-empty invite

Then no results are returned. If you run it without the "no-empty" option, you get one result:

sites/sony/modules/contrib-6--2/invite/invite.module:
 +147: Menu item titles and descriptions should NOT be enclosed within t().

sites/sony/modules/contrib-6--2/invite/invite.install:
 No Problems Found

sites/sony/modules/contrib-6--2/invite/invite_admin.inc:
 No Problems Found

sites/sony/modules/contrib-6--2/invite/invite_token.inc:
 No Problems Found

It's to do with the check on the number of results returned on line 117 of coder.drush.inc:

if (!_coder_drush_is_option('summary') && !empty($results) && (count($results) > 1 || !_coder_drush_is_option('no-empty'))) {

For cases where no problems were found, there is still one entry in the $results array for the "No problems found" text. However if 1 problem was found, then there's still one entry in the $results array and the above line prevents it from being displayed.

The attached patch should fix this.
