Convince me that nothing like the following exists in the
ports framework and /usr/src and I'd be ok with a change
*after* 4.0 release (repeats himself)
# Makefile.foo
FOOVAR=
.
.
.
BARVAR=${FOOVAR}
baz:
for i in ${BARVAR} ; do \
${BLAP} $$i ; \
done
To me, changing it right now on the eve of -release
would be gratuitous. Later I would be fine with it.
I still prefer /bin/sh being able to handle an empty
literal list but would yield to the desires of others.
