git check-ignore bug reports

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. My English is very bad, please forgive me.

environment:
  windows10
  git version 2.23.0.windows.1

for example:

.gitignore normal view --------------------------- ### Android template # Built application files *.apk *.ap_ *.aab

# Files for the ART/Dalvik VM *.dex

# Java class files *.class

# Generated files bin/ gen/ out/ release/

# Gradle files .gradle/ build/ ---------------------------
