(This is a follow-up to #353 . I can't reopen the old PR, so I file another one to address my point.)
Replace the $'\r' quoting in commit
c674b5faa3419032a6c41cc150488866f3b3cff9 with a portable alternative cr=`printf '\r'`
Although $' ' (dollar-single-quote) quoting is proposed for inclusion in POSIX, we have not seen it in a published standard yet, so it is best to avoid it for now.
