From 58729a71ce0dd0ba0bf12ca6d4ca3369bf134ac4 Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Wed, 12 Aug 2026 08:39:39 -0700 Subject: [PATCH] diff: avoid misleading statement about -l option In commit 6623a528e00b (doc: clarify documentation for rename/copy limits, 2021-07-15), the wording around rename limit options and config variables were updated to point out that only the quadratic portion of rename detection (or "exhaustive portion of rename/copy detection" as used in that commit) was limited by these options, because exact rename detection and basename-guided rename detection (which both run in time linear in the number of files) still run before this limit is checked. However, the short help message wasn't updated at the time; update it too.
