Allow monky-commit mode to toggle the full commit message

[ncalexan]

Right now, monky always shows the full commit message. I'd like to be able to toggle the "description:" section, so that we see the shortlog by default and the full log on toggle. (This is a Magit's default behaviour, and I quite like it.)

I can't reproduce this.

Can you describe exactly what you're doing?

@Wilfred thanks for the quick reply! I now see what you see -- I think I was in the middle of a monky upgrade and running a stale (very stale!) version.
