Unlike "FOO=bar cmd" one-shot environment variable assignments
which exist only for the invocation of 'cmd', those assigned by
"FOO=bar shell_func" exist within the running shell and continue to
do so until the process exits (or are explicitly unset). It is
unlikely that this behavior was intended by the test author.
In these particular tests, the "FOO=bar shell_func" invocations are
already in subshells, so the assignments don't last too long, don't
appear to harm subsequent commands in the same subshells, and don't
affect other tests in the same scripts, however, the usage is
nevertheless misleading and poor practice, so fix the tests to assign
and export the environment variables in the usual fashion.
