'printf' was introduced because it is more portable than 'echo -e'. But when the escape sequences are just newlines we can just as well use plain 'echo' (and remove the newline escape sequences). This looks cleaner than having some lines with echo and some with printf. Signed-off-by: Bjørn Forsman <bjorn.forsman@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
