+--color-words[=<regex>]::
+ Show colored word diff, i.e., color words which have changed.
+ By default, words are separated by whitespace.
++
+When a <regex> is specified, every non-overlapping match of the
+<regex> is considered a word. Anything between these matches is
+considered whitespace and ignored(!) for the purposes of finding
+differences. You may want to append `|[^[:space:]]` to your regular

+A match that contains a newline is silently truncated(!) at the
+newline.
