There is no cancel button in QtCreator's git commit or git amend. When clicking the 'x' to close the page, there's always that annoying dialog: "Git will not accept this commit. Would you like to continue to edit it?"

So a cancel button would be appreciated.

Also, it would feel more natural to have  "Git will not accept this commit. Do you really want to quit?" instead of  "Git will not accept this commit. Would you like to continue to edit it?".
