Worked on the neovim/neovim repository, focusing on improving code quality and maintainability through targeted refactoring. Addressed code complexity in the main.c file by removing an unused 'cwd' variable, which streamlined the core execution path and reduced potential sources of future defects. This change aligned with ongoing code health initiatives, ensuring that the codebase remains accessible for contributors and easier to maintain over time. The work was implemented using C, with an emphasis on code optimization and disciplined software refactoring practices. No functional changes were introduced, but the update contributed to a cleaner, more maintainable codebase for future development.
