There are a couple of properties (http.accept.*) which are unset by setting
their value to white space only.  Why not follow this convention?

Yes, help is welcome! Please open an issue to fix this on
    https://issues.apache.org/jira/projects/NUTCH
and if possible provide a patch or a pull-request on github
with the Jira issue id "NUTCH-XXX" in the title.


Thanks,
Sebastian
