patch 8.0.1276: key lost when window closed in exit callback commit https://github.com/vim/vim/commit/a3f7e58bf846b28b347a5d5b96c2d829871bd212 Author: Bram Moolenaar <Bram@vim.org> Date: Thu Nov 9 13:21:58 2017 +0100 patch 8.0.1276: key lost when window closed in exit callback Problem: Typed key is lost when the terminal window is closed in exit callback. (Gabriel Barta) Solution: When the current window changes bail out of the wait loop. (closes #2302)

" This test is in a separate file, because it usually causes reports for memory
" leaks under valgrind.  That is because when fork/exec fails memory is not
" freed.  Since the process exists right away it's not a real leak.
