Yet another spell check request

[roedygr]

I am working on a document that is half German and half English. As you can imagine, this drives the spell checker crazy.

It would be nice if <td align="top" lang="de-DE">

invoked a German language spell checker or failing that, turned off spellchecking.

I'll consider improving this for a future version, but if you use/select both English and German dictionaries at the same time, does it work well enough?
