The "dangerous behavior" may have been present in 1.7.0 already, but
1.7.3 will be the first release where this appeared to cause a real
issue. I mean, for some reason the bug (or manifestation of the
"lingering bug") first appeared on 1.7.x after r1239697 (backport of
r1237720 and r1239596 (stuff in mod_dav_svn/liveprops.c) from trunk).

Also: the problem is related to the server-side (mod_dav_svn), which
means svnrdump over serf will be problematic with 1.7.3 servers.

Disclaimer: I don't feel strongly at all about this problem, either
way. In fact, I don't really care. I just happen to be one of the few
people who can reproduce the problem, so I'm trying my best to
investigate it in any way I can and present the information.
