... and import stefanhaller's tcell fork for real rather than just replacing it This solves the problem that people trying to "go install github.com/jesseduffield/lazygit@latest" would get the error go: github.com/jesseduffield/lazygit@latest (in github.com/jesseduffield/lazygit@v0.40.0): The go.mod file for the module providing named packages contains one or more replace directives. It must not contain directives that would cause it to be interpreted differently than if it were the main module.
