Consider the following code.  I expect it to print "bad" once, but it
does so many times.  The manual is a little unclear, but seems to
imply that xpcall(f, err) only puts f in protected mode.  It shouldn't
catch errors in err.  Does that make sense?  This may be a semantic
change from 5.1, but is it still fixable in 5.2?

function t()
        error("oops")
end

function c()
        print("bad")
        error("again")
end

xpcall(t, c)
