transform result not right when transform two delta only contain retain.

[xlcs0110]

new Delta().retain(1).insert({b:2}).transform(new Delta().retain(1).retain(1,{a:1}),**false**)
// result is new Delta().retain(2).retain(1,{a:1})

new Delta().retain(1).insert({b:2}).transform(new Delta().retain(1).retain(1,{a:1}),**true**)
// result is new Delta().retain(2).retain(1,{a:1}) too.

but when delta contain "insert"
new Delta().retain(1).insert({b:2}).transform(new Delta().retain(1).insert({a:1}),**false**)
//result is new Delta().retain(1).insert({a:1})

new Delta().retain(1).insert({b:2}).transform(new Delta().retain(1).insert({a:1}),**true**)
//result is new Delta().retain(2).insert({a:1})

why the result of new Delta().retain(1).insert({b:2}).transform(new Delta().retain(1).retain(1,{a:1}),**false**) is not new Delta().retain(1).retain(1,{a:1}) too.

This is how transform for Operational Transform works. There are resources online that explains the what and why but this library just implements that. If you still think there's an error please elaborate on your rationale.
