example 'echo help | ez-ipupdate -c -' doesn't work

[Karl-Philipp Richter]

The example 'echo help | ez-ipupdate -c -' mentioned in manpage doesn't work. It results in

    -,1: unknown command: help
    commands are:
      address usage: address=<ip address>
      cache-file usage: cache-file=<cache file>
      cloak-title usage: cloak-title=<title>
      daemon usage: daemon=<command>
      execute usage: execute=<shell command>
      debug usage: debug
      foreground usage: foreground
      pid-file usage: pid-file=<file>
      host usage: host=<host>
      interface usage: interface=<interface>
      mx usage: mx=<mail exchanger>
      max-interval usage: max-interval=<number of seconds between updates>
      notify-email usage: notify-email=<address to email if bad things happen>
      offline usage: offline
      retrys usage: retrys=<number of trys>
      server usage: server=<server name>
      service-type usage: service-type=<service type>
      timeout usage: timeout=<sec.millisec>
      resolv-period usage: resolv-period=<time between failed resolve attempts>
      period usage: period=<time between update attempts>
      url usage: url=<url>
      user usage: user=<user name>[:password]
      run-as-user usage: run-as-user=<user>
      run-as-euser usage: run-as-euser=<user> (this is not secure)
      wildcard usage: wildcard
      quiet usage: quiet
      connection-type usage: connection-type=<connection type>
      request usage: request=<request uri>
      partner usage: partner=<easydns partner>
    error parsing config file "-"

which is an acceptable workaround, but a list of options without program failure would be better. Otherwise mention that this causes the program to fail.
