commit https://github.com/vim/vim/commit/49b27326447d0827c59c6cd201d58f65c1163086 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Apr 5 21:13:00 2016 +0200 patch 7.4.1712 Problem: For plugins in packages, plugin authors need to take care of all dependencies. Solution: When loading "start" packages and for :packloadall, first add all directories to 'runtimepath' before sourcing plugins.
