Don't discard commit message entered without confirmation

[focusaurus]

Is your feature request related to a problem? Please describe.

So for vim users where typing ESC to exit insert mode is deep deep muscle memory, I find myself hitting c to commit, typing a message then by reflex typing ESC and having gitui discard the message I just crafted.

Anyone else shooting themselves with this footgun too?

Describe the solution you'd like

If the commit message is still empty, OK to close with a single ESC. But maybe if there's content entered, prompt to confirm before discarding?

Describe alternatives you've considered

Well something other than ESC would solve it too but that might make the overall keybinding style inconsistent.

A clear and concise description of any alternative solutions or features you've considered.

fair point, actually this was the behaviour at some point. I agree we should go back to that 👍
