No, the behavior is intentional. Please read UPGRADE.txt. We went
through an upgrade process whereby an upgrade from 1.4 to 1.6.[0-2]
would keep the existing behavior of 1.4 Set for compatibility, though a
fresh install would have the new behavior. The default simply changed
in 1.8 so that the new behavior was now default. You can still obtain
the old behavior by using MSet or by setting [compat] app_set=1.4 in
If the help text for Set is incorrect in 1.8, then that should be fixed.
