patch 8.2.1049: Vim9: leaking memory when using continuation line

Commit: https://github.com/vim/vim/commit/b171fb179053fa631fec74911b5fb9374cb6a8a1
Author: Bram Moolenaar <Bram@vim.org>
Date:   Wed Jun 24 20:34:03 2020 +0200

    patch 8.2.1049: Vim9: leaking memory when using continuation line

    Problem:    Vim9: leaking memory when using continuation line.
    Solution:   Keep a pointer to the continuation line in evalarg_T.  Centralize
                checking for a next command.
