When testing against GNU and OpenBSD versions, "i" command was with a 2-address prefix was treated as invalid
Be compatible and treat effective address as 2nd address if 2 were specified
ed commands "a" and "i" are both handled in edInsert(), so this patch covers both
test1: "1,2i" --> 2i
test2: ",2i" --> 2i
test3: "1,2a" --> 2a
test4: ",2a" --> 2a

changes: if i or a command get two addresses, use the second one as the effective address; GNU/BSD compatibility
