This flawed error reporting is noted by two 'NEEDSWORK' comments. Address these comments by introducing two new error codes: 'READ_GITFILE_ERR_MISSING'(which groups the "file missing" scenarios together) and 'READ_GITFILE_ERR_IS_A_DIR': 1. Update 'read_gitfile_error_die()' to treat 'IS_A_DIR', 'MISSING', 'NOT_A_FILE' and 'STAT_FAILED' as non-fatal no-ops. This accommodates intentional non-repo scenarios (e.g., GIT_DIR=/dev/null). 2. Explicitly catch 'NOT_A_FILE' and 'STAT_FAILED' during discovery and call 'die()' if 'die_on_error' is set. 3. Unconditionally pass '&error_code' to 'read_gitfile_gently()'. 4. Only invoke 'is_git_directory()' when we explicitly receive 'READ_GITFILE_ERR_IS_A_DIR', avoiding redundant checks. Additionally, audit external callers of 'read_gitfile_gently()' in 'submodule.c' and 'worktree.c' to accommodate the refined error codes.
