As POSIX has not yet specified 'local', any use of 'local' already
renders the script non-conformant, so it shouldn't matter what bash does
in that situation (although if POSIX is ever going to standardize
'local', it requires some concerted effort to make all shells with
'local' to settle on a lowest common denominator).
