commit https://github.com/vim/vim/commit/21662be2211675824df1771c7f169948ede40c41 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Nov 6 14:46:44 2016 +0100 patch 8.0.0068 Problem: Checking did_throw after executing autocommands is wrong. (Daniel Hahler) Solution: Call aborting() instead, and only when autocommands were executed.
