Empty msgid in wp-admin/includes/media.php

[thenlich]

There is an empty msgid in wp-admin/includes/media.php:530

			'helps'      => __(''),

gettext("") would return the header entry with meta information, not the empty string.

• If it is not needed, but it has to be present, it doesn't need to be i18n-ed: 'helps' => ''
• If it can me omitted, we can omit it :-)
• If the idea was to let translators add a help message, but one is not needed in the English version, string description should be used: 'helps' => _c('|<helpful description of what the translators should put here>'),
