It may not be important anymore, but I've just found that I was
confusing. And I think it may be better to post again.

For "echo \t" in aubusy, it was already converted to printf in 2014.
Here is the past commit in aufs-util.git.

    bugfix: convert a few "echo"es to "printf"s
    
    While UNIX standards (IEEE Std 1003.1) describes that "echo" command
    interprets the backslash sequence unless "-n" is specified, some major
    shells don't.
    Convert them to "printf".
