patch 8.2.0928: many type casts are used for vim_strnsave() Commit: https://github.com/vim/vim/commit/df44a27b53586fccfc6a3aedc89061fdd9a515ff Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jun 7 20:49:05 2020 +0200 patch 8.2.0928: many type casts are used for vim_strnsave() Problem: Many type casts are used for vim_strnsave(). Solution: Make the length argument size_t instead of int. (Ken Takata, closes #5633) Remove some type casts.
