This method looks sufficiently similar to NativeBackendGnome::GetLoginsBetween.
Could they benefit from a shared method in PasswordStoreX::NativeBackend?

[vasilii, 2014/06/17 17:24:14]

PasswordStoreX::NativeBackend is an interface. It doesn't have any
implementation.
Actually, this method should gone. There is no GetLoginsSyncedBetween() in
PasswordStoreX::NativeBackend because it's excessive. We call it together with
RemoveLoginsCreatedBetween, therefore they should be merged. After this I can
just remove GetLoginsCreatedBetween() because RemoveLoginsCreatedBetween()
doesn't depend on it.
