Right. We've got some leftover cruft before the 9. We need to
determine whether the server is responding with that (or something
else invalid), or whether the client is mishandling the server's
response.

fetch.c:set_special_wc_prop() maps "DAV:version-name" to
"committed-rev". In trunk, I'm seeing the correct value for this
field passed over the wire:

<D:response xmlns:lp1="DAV:" xmlns:lp3="http://subversion.tigris.org/xmlns/dav/">
<D:href>/repos/!svn/bln/3</D:href>
<D:propstat>
<D:prop>
<lp1:baseline-collection><D:href>/repos/!svn/bc/3/</D:href></lp1:baseline-collection>
<lp1:version-name>3</lp1:version-name>
</D:prop>
<D:status>HTTP/1.1 200 OK</D:status>
</D:propstat>
</D:response>

Are you saying that 1.3 is not passing the expected value over the
wire or is misformatting the response?
