patch 8.0.1469: when package path is a symlink 'runtimepath' is wrong commit https://github.com/vim/vim/commit/2374faae111057ee28e8d487f9a52a95855e2206 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Feb 4 17:47:42 2018 +0100 patch 8.0.1469: when package path is a symlink 'runtimepath' is wrong Problem: When package path is a symlink adding it to 'runtimepath' happens at the end. Solution: Do not resolve symlinks before locating the position in 'runtimepath'. (Ozaki Kiichi, closes #2604)
