It is strange that this actually does work - at least in 9.0 - given that
SET ... FROM CURRENT does not seem to have any usage outside of its
interaction as part of the CREATE FUNCTION command.

Is there some use-case I am not seeing?

Since the command works I would agree that it should be provided in the
syntax section for "SET" and that a comment be added that says generally
that its presence is an historical artifact and has no real use as part of
the top-level command. Its intended use is in conjunction with the CREATE
FUNCTION command. Alternative wordings to describe uses I am not seeing are
good too.
