What flags do you pass to mergemaster while installing world?

I usually use mergemaster -iFU - the caveat being that this requires an
mtree database to be maintained for it to detect changes to files, and
this database is only built and maintained when you use the -U flag.

Presumably, freebsd-update does similar automatically, and that's why it
never asks. Or maybe it just overwrites your local changes? I've only
ever used installworld, and freebsd-update(8) doesn't mention anything
about locally modified files.
