8.2.0 psql \df+ output mangled a bit relative to 8.1.4 ...

With a database loaded into 8.2.0 from a dump from an 8.1.4 server,
"\df+ foo()", where foo()'s body has embedded tabs shows up with
those tabs escaped, whereas under 8.1.4 they were emitted verbatim:

Is there a trick to getting old behaviour back? It seems to happen
regardless of client_encoding setting (either SQL_ASCII or latin1).
Thanks!

8.2.0:
social=# \df+ housing.update_terse_listing_by_unit()
