Each caller of echo20() manually includes a space at the end of
$prefix. Would it make sense to instead have echo20() do this on
behalf of the caller?
echo "$prefix $1$1$1$1$1$1$1$1$1$1$1$1$1$1$1$1$1$1$1$1"
That wouldn't work if the prefix is the empty string; we don't want a
space in that case (see the next echo20 call below).
But ${prefix:+$prefix } would do the trick. Thanks for the idea. :)

Which would slightly reduce the burden on the caller and make it read
