"That's not a bug, it's a feature!" :-)  "a" is being assigned to $0.  If you
don't care about $0, use a placeholder: { sh -c 'echo $*' sh a b c d }*.

It would be nice if this were documented, though.  I've never seen a man page
for sh that mentions the possibility of giving arguments to a { sh -c }, and
it's been implemented slightly differently in various incarnations.
