Export an environment variable, optionally specifying a value. For
example:

* ``-x foo`` exports the environment variable ``foo`` and takes its
  value from the current environment.
* ``-x foo=bar`` exports the environment variable name ``foo`` and
  sets its value to ``bar`` in the started processes.
* ``-x foo*`` exports all current environmental variables starting
  with ``foo``.
