Thanks for your great work.

This bug is mostly fixed, but one small detail remains.  The final
jump back to the leave+ret sequence is still there.

Since leave+ret is a two-byte sequence, it makes sense to replace the
jump with a leave+ret.

Here is the -S -O2 output with gcc 3.3:

foo:
        pushl   %ebp
        movl    %esp, %ebp
        subl    $8, %esp
        cmpb    $0, 8(%ebp)
        jle     .L2
        call    a
.L3:
        leave
        ret
        .p2align 2,,3
.L2:
        call    b
        jmp     .L3

The last jmp should become

	leave
	ret
