Please, sanely wrap your lines at 80 columns when posting to the NetBSD
I believe the only person who actually suggested the above was me. It
was not the original suggestion in this thread, which was to replace
the existing /bin/ksh in base with mksh.

It's hardly the case that the ksh93 licensing is friendly. Also, it
has already been demonstrated in this thread that our existing /bin/sh
is considerably faster for most scripting purposes (including the crucial
purpose of building the system) than any of the alternatives currently
Unless that's likely to change, I would no longer support my suggestion
of replacing both /bin/sh and /bin/ksh with mksh. However, I still think
it would make an excellent replacement for the buggy old "ksh" in our
system, that is, for /bin/ksh.
Our existing /bin/sh has the full set of POSIX shell features and thus
what you can't do with it, you can't do in a portable shell script anyhow.
