showDiff\(\) can fail to highlight a char-by-char difference because Python difflib seems
don't support fully char-by-char comparison.
Please see in Python tracker:
\* issue \#1528074: "difflib.SequenceMatcher.find\_longest\_match\(\) wrong
result" \(http://bugs.python.org/issue1528074\)
\* issue \#1678345: "A fix for the bug \#1528074 \[warning: quite slow\]"
