Hi devs,
 Just tried this on Windows with trunk.
Result:

svn: E175002: REPORT of '/svn/!svn/vcc/default': 200 OK (http://svnbook.googleco
de.com)

The response to the "REPORT" request is a chunked response of zero length.
I don't know if this is legal but sounds Ok to me.
This causes ne_discard_response() to return an error as it incorrectly 
sees the "0" of the chunk length as a non zero length response.

I don't know enough about the neon library to dig further or suggest 
a patch.

Regards
Alan

This asserts:

$svn co http://svnbook.googlecode.com/svn/trunk/src/en/book@3805 && cd book && $svn up

This doesn't assert:

$svn checkout -q http://svn-qavm.apache.org/repos/svnbook/trunk/src/en/book@3805 && cd book && $svn up
