Leaving Meta Description empty

[mvlcek]

Hi!
When the Meta Desc. is empty and there is only a gallery in the contentbox something strange like this shows up in the frontend source code:

<meta name="description" content="(% gallery name=leinwaende %)" />
propose to show no meta description tag when the meta Desc Box is empty
as we dont know whats inside the content box

If you use the I18N plugin, you can use get_i18n_header(), which removes such shortcuts.
But it still uses the text of the page, if the meta description is empty.
