Vim prints options on quit

Question

I've noticed that recently when I quit vim it prints the following text to the terminal:

--- Options ---
  background=dark  helplang=en  relativenumber
  cursorline  number  scroll=11
  runtimepath=~/.config/nvim,~/.config/nvim/plugged/vim-sensible/,~/.config/nvim/plugged/vim-multiple-cursors/,~/.config/nvim/plugged/molokai/,~/.config/nvim/plugged/vim-colors-solarized/,~/.config/nvim/plugged/vim-commentary/,~/.config/nvim/plugged/lucario/,~/.config/nvim/plugged/vim-auto-save/,~/.config/nvim/plugged/vim-cpp-enhanced-highlight/,~/.config/nvim/plugged/Improved-Syntax-Highlighting-Vim/,~/.config/nvim/plugged/vimtex/,~/.config/nvim/plugged/vim-sneak/,~/.config/nvim/plugged/pretty-vim-python/,~/.config/nvim/plugged/supertab/,~/.config/nvim/plugged/simpylfold/,~/.config/nvim/plugged/vim-fish/,~/.config/nvim/plugged/vim-airline/,/etc/xdg/nvim,~/.local/share/nvim/site,/usr/local/share/nvim/site,/usr/share/nvim/site,/usr/local/Cellar/neovim/0.2.0_1/share/nvim/runtime,/usr/share/nvim/site/after,/usr/local/share/nvim/site/after,~/.local/share/nvim/site/after,/etc/xdg/nvim/after,~/.config/nvim/plugged/vim-cpp-enhanced-highlight/after,~/.config/nvim/plugged/vimtex/after,~/.config/nvim/after

I'm on a mac and I use neovim but the same behavior happens in regular vim. I don't think I changed anything recently but here is my vimrc file:

let g:vimtex_view_general_viewer

let g:vimtex_view_general_options = '-r @line @pdf @tex'

I don't see any option that could be causing it but I've tried disabling plugins randomly but couldn't come up with a thing which removes the printing

From your .vimrc:

...
set cursorline
set                " <- HERE
syntax on
...

This set command must be causing it.

Looks like during initialization Vim dumps output to terminal, but you don't see it until Vim is closed. I get similar behaviour if I put stray set to my .vimrc file (although I do need to press enter to skip the output, but this must be due to much bigger number of changed options).
