Umlauts not supported in "listings.sty" - fix included

[Julian Bangert]

Binary package hint: texlive-latex-recommended

Ubuntu 10.04 Alpha, should also occur on 9.10.
Version 2009-7 of texlive-latex-recommended.
I ran a document including listings from a file with umlauts throught pdflatex.
I expected it to work like a breeze, as I had utf loaded, etc...

However, I got numerous obscure errors, mostly about undefined unicode characters.

Can be fixed by applying the following patch:
