From: Johannes Schindelin <johannes.schindelin@xxxxxx>
When showing what changed between old and new commits, we show a diff of
the patches. This diff is a diff between diffs, therefore there are
nested +/- signs, and it can be relatively hard to understand what is
going on.
With the --dual-color option, the preimage and the postimage are colored
like the diffs they are, and the *outer* +/- sign is inverted for
clarity.
