Correction: 5.2.0-beta-rc5 now prints "removed function" here because
setfenv is a removed (not deprecated).  However, for a function that
is deprecated, we get this:

> =module"foo"
table: 0x934b440

and if we disable LUA_COMPAT_ALL, then is does this:

> =module"foo"
stdin:1: deprecated function
stack traceback:
	[C]: in function 'module'
	stdin:1: in main chunk
	[C]: in ?

which I found a bit odd that the message about a function being
deprecated is an error rather than a warning (contrast to other
languages [1-3]).
