vim-patch:7.4.1097 Problem: Looking up the alloc ID for tests fails. Solution: Fix the line computation. Use assert_fails() for unlet test. https://github.com/vim/vim/commit/065ee9aebf9abe08ae8c0dba7d05cbdcc423c8e0 Use v:count and v:errmsg instead of count and errmsg.

vim-patch:8.2.0401: not enough test coverage for evalvars.c Problem: Not enough test coverage for evalvars.c. Solution: Add more tests. (Yegappan Lakshmanan, closes vim/vim#5804) https://github.com/vim/vim/commit/8dfcce3a78ccb520cc9d09081f998091494c50bf Assert E475 instead of E474 in :redir test because a later patch changed the error number. Comment out the test for :echo with a deeply nested container as Nvim implements :echo very differently.
