The change you suggested is also what I tried first. Looks like it depends on the
shell. On my system /bin/sh is a symlink to /bin/bash and that is the behavior
I observed. On other shells the assignment is not passed to the environment of
the called procedure at all.

Here is an example script:

	#!/bin/sh
	test_must_fail () {
		"$@"
		test $? -gt 0 -a $? -le 129
	}
	foo='wo adrian'
	foo='yo adrian' test_must_fail sh -c 'echo foo: $foo'
	echo "foo: $foo"

When /bin/sh is a symlink to bash, I get:

foo: yo adrian
foo: yo adrian

If I change #!/bin/sh to #!/bin/bash I get what is expected:

foo: yo adrian
foo: wo adrian

#!/bin/ksh
foo:
foo: yo adrian

#!/bin/dash

foo:
foo: yo adrian
