patch 8.1.0020: cannot tell whether a register is executing or recording commit https://github.com/vim/vim/commit/0b6d911e5de1a1c10a23d4c2ee1b0275c474a2dd Author: Bram Moolenaar <Bram@vim.org> Date: Tue May 22 20:35:17 2018 +0200 patch 8.1.0020: cannot tell whether a register is executing or recording Problem: Cannot tell whether a register is being used for executing or recording. Solution: Add reg_executing() and reg_recording(). (Hirohito Higashi, closes #2745) Rename the global variables for consistency. Store the register name in reg_executing.

" 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.
