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.
