Doesn't work with nvim and vim-plug

[FalcoGer]

When sourcing the file directly the script works fine, but when using vim-plug and loading this as a plugin with

Plug 'guns/xterm-color-table.vim'

the script behaves erratically. Sometimes it pastes the color table at the top of the current buffer when invoked with :XtermColorTable, especially if the XtermColorTable buffer has been deleted and sets the buffer to not modifiable. Of course this completely destroy the work. It looks something like this.

It also opens a new tab for no reason. The split versions open a new split, but only if the XtermColorTable buffer already exists, but sometimes it remains empty. It's a complete mess.

It might be a problem with nvim, or an incompatibility with bufferline. Not sure.

Turns out sourcing the file directly produces the same bug. I have disabled all plugins and the bug still occurs. It seems like this is a problem with nvim. Ind it's reproducible like this

1. nvim /some/file/that/exists
2. :XtermColorTable

Result:

• A new buffer is opened in the current window with name XtermColorTable
• That buffer is empty
• The buffer is set visible in the current window
• A new tab is created
• The new tab keeps the current file
• The color table is pasted at the top of the file
• the file is set non-modifiable

Expected result

• new buffer is created
• color table is put into that new, empty buffer.

Turns out this was the culprit

augroup AutoNewTab
    autocmd!
    " autocmd BufAdd,BufNewFile * nested tab sball
    autocmd BufNewFile * nested tab sball
augroup END

But I don't need it anymore since i use bufferline now.
