Diff to second parent when committing a merge
Created originally on Bitbucket by afriza (Afriza N. Arief)
Currently the diff to first parent and to second parent are shown one after the other in the tab(s) on the bottom right of the Commit Dialog.
I think having a tick box "Diff to second parent" similar to the Repository Explorer will be more user friendly.
And the file list should probably change accordingly when the check box changes.
