[Adding dev_at_s.a.o as I think this is a bug in the Subversion code,
although I don't know enough to be sure.]

As far as I can see mod_dav_svn.c:dav_svn__handler passes all POST
requests to dav_svn__method_post and that function will return an error
if the request does not have SVNPath or SVNParentPath set since it will
fail to open a repository.
Is that the behaviour we want? I don't think we should be attempting to
handle POST requests that are directed at non-Subversion locations.
Should one of those functions simply ignore the POST request when
neither SVNPath nor SVNParentPath is set?
I see we register the hook using APR_HOOK_LAST. Does that mean we
expect other hooks to get in first and handle non-Subversion POST
requests? What happpens if the other handler also uses APR_HOOK_LAST?
Does it then depend on the order of the module loads? Is it random?
