Who exactly is clamoring for ksh93 statements in the opensolaris.sh config
file?

Plenty of developers are already building using the existing nightly with
ksh93.  Problems like the one you cite above are cosmetic and do not
interfere with development.  On the other hand, large changes like what
you are ultimately proposing (not just with this first wad) are much more
likely to cause serious problems -- and as more obscure ksh93 incantations
get added, it will be increasingly hard for others to understand and fix
these problems.

Our goal for nightly should be to make it simpler to understand, not to
rewrite it in a language few in our community have expertise in.
