Some problems with updates over ra_dav

Hello

Following the 'UU' problem I reported yesterday with ra_dav I have
checked-out a pristine copy of Subversion and built that.

The first problem I observed while investigating my 'UU' problem, I
tried updating autogen.sh in the subversion tree and a spurious
modification appears

$ svn st autogen.sh
__ autogen.sh
$ svn up -r1805 autogen.sh
_U ./autogen.sh
Updated to revision 1805.
$ svn st autogen.sh
M autogen.sh
$ svn up autogen.sh
_U ./autogen.sh
Updated to revision 1831.
$ svn st autogen.sh
M_ autogen.sh
$ svn diff autogen.sh
Index: ./autogen.sh

The second problem is the one I reported yesterday, running 'svn up'
on a file with property mods only causes 'UU' to be displayed instead
of '_U'. This causes prop_tests.py to fail over ra_dav. Enabling
neon session debugging I see what I think is a server problem

Here is part of the autogen.sh update that produces '_U'

Here is part of the update that my local subversion server generates
for a file that only has property changes.

Got 573 bytes.

Note the extra <S:fetch-file/>. I don't really follow all the DAV/HTTP
stuff but I think that is responsible for the client sending a GET
request and thus producing 'UU' instead of '_U'. Note that a similar
update over ra_local displays '_U' so I think the repository does
contain only a property change.

Both problems should be easy to reproduce: just update autogen.sh as
above, or run prop_tests.py over ra_dav.
