Modified Files:
        src/bin/ksh: expr.c

Log Message:
Fix core dump caused by
        ksh -c '(i=10; echo $((++-+++i)))'
reported by Steffen Nurpmeso (not on a NetBSD list or PR).

Seems pointless to fix just one of the bugs in this thing, but this one was
easy enough (and stupid enough).   (The "i=10" part is unimportant, as is the sub-shell).
