git check-ignore bug reports supplement

[L]

When the gitignore file has consecutive ^M$ special symbols, running the "git check-ignore '<pathname>/'" command will prompt '<pathname>/' exists (even if it doesn't exist), and prompts '<pathname>/' in the last consecutive ^M$ location.
Noto: All command run in GitBash.
