Ah, yes, this is true.  The statement about "\r" is also true for Linux
with POSIXLY_CORRECT, IIRC.

It's nice to have a way to reproduce without having a separate
toolchain.  Thanks for the suggestion.

Unfortunately, printf is not specified by POSIX to take hex escapes, so
this, too is nonportable.  We are unfortunately allowed to use only
octal escapes (yuck).  However, we can write this:

  cr=$(printf '\r')

or

  cr=$(printf '\015')

I think the former is clearer, since that's what we were writing before.

The latter however appears more portable at least to traditionalists
;-)
