Right. Come to think of it, many other GNU programs simply use
fprintf() family of routines and if GLIBC and/or
native libc supports the positional parameters, then the
message using $1%d, etc. will work. So presumably for other
tools such positional parameter usage is not so strange.

I will post a few other findings about decoders in
responses to other replies.
