erlang_complete#Complete(1, '') return the wrong index

[damnever]

For example:

-module(xx).
-export(main/0).

main() ->
    io:

I think it should return 4 rather than 7.

Could you elaborate on why you think that would be better?

The other completion framework may depend on it, such as completor.vim.
