index: replace insert(-1, e) method by append(e) method

I want to make index[len(index) - 1] be the tip revision, not null
revision as it is today. insert(-1, e) will then make little
sense. Since insert() currently requires the first argument to be -1,
it seems simpler to replace it by a method that allows insertion only
at the end.

Note that revlogoldindex already has this method (by virtue of
extending list).
