For the git migration we want a nice clean repository with UNIX line endings. git does not use svn:eol-style, we just need the file contents to be sane. Sorry everybody. I know this messes up blame. Scumbag *NIX developer says migrating to git will make line ending issues go away; commits giant change to svn which changes line endings anyway. :) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30924 a1c6a512-1295-4272-9138-f99709370657
