${*} causes syntax error

[illiliti]

sample:

: ${*}

output:

dash, ash, mksh, oksh, yash, zsh(--emulate sh):

<no output>

mrsh:

test.sh:1:5: syntax error: expected a parameter

Note that parameter expansion of $* [0] result in undefined behavior. ${*} isn't a parameter expansion. It's a safe alias to $*
