Are you sure that "word" here means one or more tokens, or zero or
more tokens. If it means zero or more tokens, then 'for i in ; do '
is perfectly legal. You're not quoting what word means.
The reason that I ask this is that I can't see why
for i in ; do
would be any different than
for i in $foo; do
when foo is empty. They are the same thing from at last my world view
of the shell.
