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.
