[Eeglablist] adding events to an EDF data without events

Hi Stephen and Makoto,

Thanks you both for the suggestions.

1. Can you show me how to create a dummy event? Command line works for me.
I only use the GUI to add events while paging thru the EEG waveform.

The code Stephen shared didn't work for me. I got the error

Getevent: cannot deal with empty event structure

2. Bug 1838 has been created.
