Display the diffs for a merge in a unified fashion.
Stuff that ended up in the result is shown in bold with a "+" at the beginning of the line; stuff that didn't is in the normal font with a "-" at the beginning of the line. The color shows which parent the stuff was in; red for the first parent, blue for the second, then green, purple, brown, and the rest are grey. If the result is different from all of the parents it is shown in black (and bold).
