I don't think changing this to match POSIX would break anything, as at the
moment redirections following a functon definition are pretty much useless.

In section 3.9.5 of the Posix shell standard,
it defines the syntax as
fname() compound-command [io-redirect]
and it says that the option io_redirect shall be performed during the
execution of the function itself.
