patch 8.0.0241: fallback implementation of mch_memmove is unused commit https://github.com/vim/vim/commit/52c0de1de196120976fef82cbbaaeafbedd9c62f Author: Bram Moolenaar <Bram@vim.org> Date: Thu Jan 26 21:36:34 2017 +0100 patch 8.0.0241: fallback implementation of mch_memmove is unused Problem: Vim defines a mch_memmove() function but it doesn't work, thus is always unused. Solution: Remove the mch_memmove implementation. (suggested by Dominique Pelle)
