Indeed, portable sh scripts should be using printf instead of echo,
every time.

echo(){ printf '%s\n' "$@"; }

yields a well-behaving "plain" echo variant.

If one needs some special tricks, printf covers more cases than echo anyway.

I may be wrong but I am not aware of a "nowadays practically useful"
platform where printf is not available (even if we do not consider a
possibility to make it available).
