A fix has been commited on -current :

Modified Files:
        src/bin/sh: expand.c

Log Message:
"for i in ${x-a b c}; do echo $i; done" should print "a\nb\nc\n" not "a b c\n"
like other shells do. mark the expansion for ifs splitting. XXX: linux has a
very complicated fix for this. I wonder why.

It works better now.

address@hidden [~]> /bin/sh 
$ for i in a b c; do echo $i; done
a
b
c
$ for i in ${x-a b c}; do echo $i; done
a
b
c
$ x='x y'
$ for i in ${x-a b c}; do echo $i; done
x
y
