Unclear What Claude Code does differently with variables sorted as file paths is not known.
What
Claude Code sorts some environment variables (named values your system passes to programs) by whether they point to a file or a folder. GIT_CONFIG_GLOBAL and GIT_CONFIG_SYSTEM, which tell Git where its configuration files are, are now sorted as file paths, alongside variables such as JAVACMD and CLOUDSDK_PYTHON.
Why
These two variables are now handled the same way as other variables that point to a single file.
