From: Johannes Schindelin <johannes.schindelin@xxxxxx> When displaying a diff of diffs, it is possible that there is an outer `+` before a context line. That happens when the context changed between old and new commit. When that context line starts with a tab (after the space that marks it as context line), our diff machinery spits out a white-space error (space before tab), but in this case, that is incorrect. Rather than adding a specific whitespace flag that specifically ignores the first space in the output (and might miss other problems with the white-space warnings), let's just skip handling white-space errors in dual color mode to begin with.
