DPK or DGK?

What I have suggested is that ALL echo commands be given both -n support
(for V7/BSD compatibility) and -e support a la V8/V9.  That would provide
a migration path for shell scripts and allow reasonable default behavior
for some future merged version of "echo" instead of escape mapping a la
SysV.
