Ability to "expand commit description" by default

[sepehr]

Body

What are you proposing?

I noted that in recent versions of the editor, the commit description is by default folded. One needs to find and click the little "expand commit description" every time to see the description.

Additionally, the line breaks in the description are not expressed in the UI and are rendered continously.

Considering my 50/72 commit convension, this has become an annoyance and I could not find a config directive to change the behavior.

Possible approach

Introduce config directives one can tweak to modify the behavior.
