Neovim Nightly Issue

[Parham Alvani]

I am using Neovim Nightly and have the following error:

Error detected while processing /home/parham/.local/share/nvim/site/pack/packer/start/vim-gitgutter/plugin/gitgutter.vim[109]..function gitgutter#highlight#define_signs:
line    1:
E475: Invalid argument:

This happens to me after the following commit on the neovim.

neovim/neovim#25724

I guess defining an empty sign now incorrectly causes an error.
Will be fixed in Neovim.

Thanks for flagging this. I've opened #876 here to use extmarks instead of legacy signs where available.
