This is obviously wrong. This patch fixes this. [...]
Well, if IFS is empty, field splitting is disabled. There's nothing in POSIX that clearly says that $@ and $* should expand to the positional parameters *as separate arguments in list contexts*. yash and the Bourne shell behave like dash. Only shells with array support behave differently. The whole $*/$@ expansion is rather unclear in the POSIX spec. I've just raised the problem on the Austin group mailing list.
