[Error] Cannot find index file: .../.git/index

[tamago324]

Describe the bug

Opening a file in a git project that has never been committed will result in an error
If ./git/index does not exist, an error will occur.

To Reproduce

init.vim:

let $PLUGIN_DIRECTORY = '~/.config/nvim/.plugged'
set runtimepath^=$PLUGIN_DIRECTORY/plenary.nvim
set runtimepath^=$PLUGIN_DIRECTORY/gitsigns.nvim

lua << EOF
require('gitsigns').setup {
  -- config
}
EOF

Steps to reproduce the behavior:

1. Make empty git project: $ mkdir sample_proj && cd $_ && git init
2. Create file: $ touch file.vim
3. Start nvim: $ nvim -u ~/tmp/init.vim -i NONE file.vim
4. See error

You are making an error, explicitly.

gitsigns.nvim/lua/gitsigns.lua

Lines 326 to 330 in b8ff522

	local index = gitdir..'/index'
	if not path_exists(index) then
	error('Cannot find index file: '..index)
	return
	end

I'm really sorry.
I am so embarrassed.

As a suggestion, how about using print instead of error?
I was a little concerned about getting an error every time I open a file.

[tamago324]

In case of an error(), I had to press Enter each time, which I found annoying.

Thanks for this. I haven't considered this scenario. I'll reopen and try and fix this.

Also many thanks for the minimal steps to reproduce. That makes dealing with this so much easier!

Thank you very much.

Thanks to the issues template, I was able to quickly create issues.

I'd noticed this bug too, but had been too busy to eliminate wether there was an issue in my setup (I'd been playing with the statusline handlers at the time). FWIW I believe the last commit before this issue was:

Could someone kindly try out #50, It should fix this issue.

@lewis6991 Thank you! I have confirmed that it has been fixed 👍
