I conducted another experiment:
cp /bin/ls /usr/lib/libssh.so.2 
apply freebsd-update fetch install

And freebsd-update did replace the bogus /usr/lib/libssh.so.2.
So I can conclude that it WILL replace modified files (unless they are
listed in UpdateIfUnmodified).

I have not yet understood freebsd-update.sh well enough to figure out
how it finds modified files. However, it seems safe to be used after a
buildworld.
