If the test runner is under heavy load, the command we are testing may
succeed in printing to stdout before the dummy receiver has terminated.
Add a short delay to reduce the likelihood of this happening.

* The `env` utility's inability to run a command whose name contains an
equal sign is a feature, not a bug, so move that paragraph up from the
BUGS section to the DESCRIPTION section.
* Mention that this can be worked around by prefixing the command name
with `command`, and add an example of this to the EXAMPLE section.
* Add a test case which verifies that `env` does not run a command with
an equal sign in its name even if it exists, and also demonstrates the
workaround.
