patch 8.2.0056: execution stack is incomplete and inefficient Commit: https://github.com/vim/vim/commit/1a47ae32cdc19b0fd5a82e19fe5fddf45db1a506 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Dec 29 23:04:25 2019 +0100 patch 8.2.0056: execution stack is incomplete and inefficient Problem: Execution stack is incomplete and inefficient. Solution: Introduce a proper execution stack and use it instead of sourcing_name/sourcing_lnum. Create a string only when used.
