Remarks:

The name current_dir: Only the value of variable current_dir indicates that this is a boolean.

System call vim.loop.os_uname() is always executed, also when current_dir is not supplied.
Would this approach be appropriate?

Thanks for the PR!

I appreciate the exact copy of the approach from 'mini.starter' (I'd usually do that too), however I think the better approach here is to use plain vim.startswith() with cwd .. '/'. As far as I remember, built-in paths coming from Neovim always use forward slash. If not, we'll wait for a Windows user to report.

I've merged in the temporary branch to polish up a bit.

Thanks again for following through!

This should now be part of latest main.

Thank you!
