patch 8.2.1870: Vim9: no need to keep all script variables Commit: https://github.com/vim/vim/commit/39ca4127a094d8aca6f77c01be4f3fea506d5cb7 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Oct 20 14:25:07 2020 +0200 patch 8.2.1870: Vim9: no need to keep all script variables Problem: Vim9: no need to keep all script variables. Solution: Only keep script variables when a function was defined that could use them. Fix freeing static string on exit.

" Settings for test script execution
" Always use "sh", don't use the value of "$SHELL".
set shell=sh

" Only when the +eval feature is present. 
if 1
  " While some tests overwrite $HOME to prevent them from polluting user files,
  " we need to remember the original value so that we can tell external systems
  " where to ask about their own user settings.
  let g:tester_HOME = $HOME
endif
