Consistency: everybody else in the test script contrasts "actual" vs
"expect" (they happen to be of the same length ;-); don't say
expectED just to be different.

Portability: "VAR=VAL shell_function args..." does not work
everywhere, unlike "VAR=VAL command args..." that exports the set of
environment variables for just a single shot invocation of the
command.
Running this script with dash fails, even though bash does behave as
you expect.

Taking them together, here is what I'll be queuing on top to make
today's push-out to pass the tests.
Thanks.
