btrfs-progs: Documentaion: rename to .asciidoc
A few minor benefits: * editors set highliting according to the extensions * web access to the git repository (github) renders the .asciidoc files: * we can link to them from the wiki * the files are editable via browser and such editations can be submitted for merge easily Signed-off-by: David Sterba <>
