Non-portability might be tolerable if there was some explicit switch
required to turn on support for the non-portable bits. It's not as
if FreeBSD startup scripts need to be run in many environments with
many different sh's.
If portability is a concern for reasons I am missing, then zsh and
ksh both contain parametere expansion flags for case manipulation.
That line of reasoning leads to quite a different bikeshed, however.

Me neither.
