I have this issue where noexpandtab turns itself on after a while. Tried to describe it here and in the Github Issue because I am not 100% sure this is a legit bug.For a long time, I have disregarded this thinking it is some plugin acting up. But then a friend who uses fairly minimalistic Neovim setup shared his frustration for the same behaviour.It goes like this  you go about your work day and at some point in time it starts using tabs instead of spaces in all files. So I have to issue:set et:retabTo get the current file back on track, but the problem is the new noexpandtab setting becomes  global after that, so in the end I just restart Neovim. It might, of course, be a faulty plugin, but if this is actually a bug then more people should have been experiencing it.The list of plugins that are common between our configurations:AndrewRadev/splitjoin.vimAndrewRadev/vim-ecoShougo/deoplete.nvimXuyuanp/nerdtree-git-pluginairblade/vim-gitgutterjunegunn/fzfkana/vim-textobj-userkchmck/vim-coffee-scriptmtscout6/vim-cjsxmxw/vim-jsxscrooloose/nerdtreetpope/vim-abolishtpope/vim-dispatchtpope/vim-fugitivetpope/vim-repeattpope/vim-surroundvim-airline/vim-airlinevim-airline/vim-airline-themesvim-ruby/vim-ruby
