Hi dan,
i think you try to solve a problem that has no proper solution. Writing a
script that circumvents all bugs on different sh implementation will be hard at least.

1. Does ignoring  '-n' have any serious problems ? If solaris/AIX/xyz produces a not so nice
   output, who cares  ???

2. If you need that feature:
The most easy way is to provide an simple echo cmd for systems that have a broken echo support,
next best provide your own shell (busybox comes to my mind).

just my 2 cents,
