From d6f406db4527deb693f0aef90316c25d846f5195 Mon Sep 17 00:00:00 2001 From: zeertzjq Date: Tue, 26 Mar 2024 13:31:37 +0800 Subject: [PATCH] fix(filetype): don't use fnamemodify() with :e for extension (#27976) Use pattern matching instead, as fnamemodify() with :e produces an empty string when the file name only has an extension, leading to differences in behavior from Vim.
