Bug: netrw buffer for directory appears in tabline buffer list

[salcode]

How to Recreate

• Open a file in Neovim
• Hit - to trigger netrw
• Navigate to another filename and click Return

Expected Behavior

There should be two buffers in the tabline at the top of the editor, one for each file

Actual Behavior

There are three buffers in the tabline at the top of the editor, one for each file plus one for the directory.

See tpope/vim-vinegar#13

Possible Solution

The vim-vinegar thread includes the suggestion of adding

vim.g.netrw_fastbrowse = 0

If we add this we should:

• create a file at lua/config/vinegar.lua
• add the above setting line to this new file
• load this new file as the config for the vim-vinegar plugin in

  salcode-nvim/lua/plugins.lua
