Yes. I’m even prepared to fight POSuX on some of the things
they mandate that would require different behaviour across
platforms, and, if necessary, be not compliant. This is a
feature, and really a big one, trust me.

Implicit CR stripping WILL break existing scripts. I know
of at least one.

tr -d \\r would work, too (but also strip CR in the middle).

Quick hack (needs just a POSuX shell and no local builtin):

mkshdos_re=$(printf 's/\r$//')
mkshdos() {
       if test -n "$1"; then
               mkshdos_fn=$1
               shift
       else
               mkshdos_fn=-
       fi
       mkshdos_T=$(mktemp /tmp/mkshdos.XXXXXXXXXX) || {
               echo >&2 mkshdos: Error: Could not create temporary file.
               return 255
       }
       sed "$mkshdos_re" <"$mkshdos_fn" >"$mkshdos_T"
       mksh "$mkshdos_T" "$@"
       mkshdos_rv=$?
       rm -f "$mkshdos_T"
       return $mkshdos_rv
}

Please forward this.
