As I just replied to Julian, I believe an 'svn update' should always
make BASE reflect the repository. Local-mods are simply rewritten in
terms of the new BASE, possibly recording conflicts in that process.

In my note to Julian, I suggested that we update B/f to be a move from
A/f_at_4 (and then reapply any local-mods). That would become the
"default" resolution, which matches Stefan's preference. Conflict
resolution could convert it into a copy of A/f_at_3 and restore A/f_at_4.
