GNU 'diff -u' prefixes each line with either a space, a '+', or a '-'.
UnifiedDiffFormatter does the same, but it also adds an additional column of
whitespace between the prefix and the line. GNU diff only does that in
non-unified mode.
Fix this by implementing lines() in UnifiedDiffFormatter, overriding the parent
class implementation.
