Rewrite texts at theme pages

-      $output = '<p>' . t('Set and configure the default theme for your website.  Alternative <a href="@themes">themes</a> are available.', array('@themes' => 'http://drupal.org/project/themes')) . '</p>';
+      $output = '<p>' . t('Select the themes to use for this website. You can <a href="!settings">configure</a> site-wide display settings or configure themes individually. Note that different themes have different regions available for displaying data.', array('!settings' => url('admin/appearance/settings'))) . '</p>';

api page on t() suggests using @placeholder for urls

I'm guessing you guys saw this issue : #504080: Improve Themes Admin Description The patch was committed only a few hours before this came out. Lengthy discussion on there.

At any rate, I tested this patch and I don't see the line that mentions contributed themes, as you show in your theme settings page 'after' screenshot.

[Edit: WEIRD, that is not my screenshot, lol. it was a dumb file name, ofc. but embedded it before upload, and obviously the name was taken]

Screenshot *really* attached now!

Can we restrict the scope of this patch to the settings page?

We fixed it already. If there is something specific about the settings page, please open an issue about that.
