Unable to quit vim after editing files outside DokuWiki

[alazyworkaholic]

The following commands will leave you stuck in DokuVimKi without being able to quit. Even qa! seems to be reinterpreted to DWquit!, which results in the same errors.

:Doku
:DWedit playground
:sp 
:e anyname
:ls
 10 #a    "playground"  line 1
 11 %a    "anyname"     line 1
:bd 10

:DWquit
Some buffers contain unsaved changes. Use DWquit! if you really want to quit.

:DWquit!

It looks like the problem is manually deleting the buffer. When you exit, we try to delete this buffer since it's still in DokuVimKi's buffer list, but no longer in vim's.

Solving this properly would require DokuVimKi intercepting a buffer delete and removing a deleted buffer from its state. Not sure this is even possible.

I will try simply ignoring the failure on buffer deletion.
