From 40b30f245d57f89215f89c29b72e8b557f09b82a Mon Sep 17 00:00:00 2001 From: Pushkar Singh Date: Sat, 21 Feb 2026 11:05:12 +0000 Subject: [PATCH] path: factor out skip_slashes() in normalize_path_copy_len() Extract skip_slashes() to avoid repeating the same is_dir_sep() loop in multiple places inside normalize_path_copy_len(). Keep the dot-component handling inline to preserve the original control flow and readability, as suggested in review. No functional changes. Behavior verified with t0060-path-utils.sh.
