Standardize line endings of wp-config-sample.php and wp-fullscreen.css

[xknown]

Two core files seem to have invalid line endings (\r).

~/data/wp$ ack -l "\r"
wp-includes/js/tinymce/plugins/wpfullscreen/css/wp-fullscreen.css
wp-config-sample.php

~/data/wp$ cat -vT wp-config-sample.php | head
<?php^M

Add a more descriptive summary.

wp-fullscreen.css definitely should be LF line endings (perhaps svn:eol-style: native is missing on some new files) but wp-config-sample.php is deliberately CRLF.

More files (other than wp-config-sample.php) that probably need svn:eol-style:native.

/data/wp$ find . -type f | grep -v .svn | xargs svn propget svn:eol-style | grep CRLF
wp-includes/images/crystal/license.txt - CRLF
wp-includes/js/scriptaculous/MIT-LICENSE - CRLF
license.txt - CRLF
wp-config-sample.php - CRLF

I didn't think about that some Windows users use notepad to edit their wp-config.php file

Any user-readable files should be CRLF for maximum compatibility, ie. wp-config-sample.php and any license files. Not all license files are CRLF though i don't think, The only change here should be to make all the license files consistent.
