jumping with <s-tab> and <c-g>g doesn't work when both delimitMate_expand_cr and delimitMate_jump_expansion are set

[grr]

This is similar to #222, which the reporter closed without comment, so it's unclear if or how that was resolved.

with:

function() {
    function() {
        |
    }
};

shift-tab results in:

function() {
    function() {
        
        |  }
};

also, <c-g>g has no effect in this case.

tested on terminal vim and macvim 8..0.1633 with only delimitMate and pathogen installed.
relevant settings:
let g:delimitMate_expand_cr = 1
let g:delimitMate_jump_expansion = 1
