  1. open tagbar
  2. split tagbar window
  3. open tag inside of tagbar
  4. Error message w:autoclose undefined. jump fail

root cause
at
function! s:JumpToTag(stay_in_tagbar) abort
let taginfo = s:GetTagInfo(line('.'), 1)
let autoclose= w:autoclose

solution
check whether w:autoclose existed

let autoclose= exists('w:autoclose') && w:autoclose ? 1 : 0

Potential fix for preservim#772 - InitWindow issue

Potential fix for preservim#772

This issue is being caused by the InitWindow() routine not being called
when a split of the tagbar window occurs. This will potentially fix that
issue by forceably calling s:InitWindow() when a new tagbar window is
found.

Note however, that when closing one of the split tagbar windows, it does
cause the other one to close as well. It looks like there is an issue on
the close processing that it identifies all windows that have the tagbar
buffer loaded as the tagbar window.

I have pushed up a potential fix. There are a lot more than just the w:autoclose that are not set. To properly fix this I think we'd need to call the s:InitWindow() when a split occurs. The PR can be used as a baseline, but I haven't fully tested everything or fully examined the implications. On basic testing it does appear to fix the issue though and the split works successfully after this patch.
