Minor wording inconsistency: Confirmation prompts

When I push a branch that I've rebased, then I get a popup telling me that there is a problem, and that I can use 'enter' to force-push, or 'esc' to cancel.

When I rebase the current branch onto another branch, I get a popup asking me whether I'm sure. I can use 'enter' or 'y' to confirm (haven't tried any other keys) and 'esc' to abort (haven't tried 'n' yet).

I feel these two situations are quite similar, and essentially both of these are confirmation dialogs. I feel that either both should tell me which keys to use, or neither.

My personal preference would be a suffix that indicates which keys are possible:

```
Are you sure you want to do this? [Y/n]
```

The square brackets would list the possible answers, and the uppercase letter indicates which one is the default (i.e. used when hitting enter).

Or there is a dialog that includes actual buttons and tab is used to navigate between them, but maybe that's more effort than just rewording the string...
