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.
Potential fix for #772
