patch 8.2.4742: there is no way to start logging very early in startup Commit: https://github.com/vim/vim/commit/c9a9a0ac1ec3b985d38c01ddf9f0ba2f15386f34 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Apr 12 15:09:23 2022 +0100 patch 8.2.4742: there is no way to start logging very early in startup Problem: There is no way to start logging very early in startup. Solution: Add the --log argument. Include the date in the start message in the log file. Avoid a duplicate message when forking. Log an executed shell command.
