I agree echo is an abomination. Especially with POSIX saying things
like "If the first operand is -n, or if any of the operands contain a
<backslash> character, the results are implementation-defined." The
best thing we can do is not use echo in any scripts.

I think from a philosophical standpoint sbase echo should not include
-n, to be simpler and still POSIX compliant. However pragmatically
many scripts use echo -n so I think it makes sense to keep it.

I side with Mattias on this one. Accepting -- even in utilities that
don't have flags has the benefits of 1) complying with POSIX so we can
be a drop in replacement 2) consistency with all the other tools.
