Thanks - I pushed this which is very slightly different but should
still work:

http://git.annexia.org/?p=virt-what.git;a=commitdiff;h=b7cc3d93a613ef6d0ac5ccd6e32cc3d66e057243

The differences are:

* Added ( .. ) 2>/dev/null around the HTTP request, so that if it
  fails then the output of virt-what does not contain an error
  message.  This also fixes the test.

* Removed extra whitespace.

* Added documentation.

Rich.
