The heuristics didn't work this time. :-(

FreeBSD Update tries to guess what users want to have done -- in this case,
the heuristic is "if a configuration file is present in release X but not
in release Y, it's probably not relevant in release Y; so let's delete it".
The case of a default configuration file being moved from /etc/ into
/usr/share/examples/etc is one which I didn't consider; but I think the
general heuristic is a good one (consider the scenario where a /etc/foo.conf
is renamed to /etc/food.conf -- with the current heuristic, at least the
user gets a warning that the file is disappearing rather than suddenly
finding that the foo daemon isn't starting up properly for no apparent
reason).
