Dialog are too wide when take the "reset xxx to this commit" action

When take the "reset xxx to this commit" action and the commit message is very long, the dialog will be too wide to displayed in the screen (the OK button will be out of the screen). Because in the "To commit" line in the dialog, all of commit message will be displayed and will not wrap, the dialog will be as long as the commit message. The solution is wrapping line if the commit message is too long or simply displayed part of the commit message with an ellipsis or use a text field with a vertical scrollbar.
