Failure to load tagbar from nested BufWinEnter autocmd

[fritzophrenic]

I was using a nested BufWinEnter autocmd to launch Tagbar on certain file types.

On updating from changeset 3634e7ab4feeab8ad49166e9e716638c20f1637c to the latest, Tagbar stopped opening. Indeed, it would set the filetype incorrectly to Tagbar on the newly opened code file instead of the code file getting the correct auto-detected file type!

I found the first "bad" change using git bisect:

git.exe bisect bad

7c5606668526c999c9a5c72ff1ec23300ae2a60f is the first bad commit

Give each tab its own tagbar buffer

Success (2094 ms @ 12/13/2018 10:49:57 PM)

After reading issue #501 I tried deleting the "nested" keyword from my autocmd, and it seems to work now. I'm not sure whether the code needs an update to make this work again, or if the documentation needs an update to remove "nested" from the suggested autocmds.

For reference, here's the offending autocmd:

      let g:funclist_cmd_open = 'call tagbar#autoopen()'
      " ...
      autocmd BufWinEnter *.{h,c{pp,}}{@@/*,} nested
            \ if winnr("$") < 2 && !&diff && exists('g:funclist_cmd_open') |
            \   exec g:funclist_cmd_open |
            \ endif

@fritzophrenic are you still seeing this issue? or were you able to get everything working correctly?
