t0000: test multiple local assignment

According to POSIX enhancement request '0000767: Add built-in "local"'[1], dash only allows one variable in a local definition; it permits assignment though it doesn't document that clearly. however, this isn't true since t0000 still passes with this patch applied on dash 0.5.10.2. Needless to say, since `local` isn't POSIX standardized, it is not exactly clear what `local` entails on different versions of different shells. We currently already have many instances of multiple local assignments in our codebase. Ensure that this is actually supported by explicitly testing that it is sane.
