**Description:**
News feed readers and Mozilla Thunderbird e.g. do show a colored revision comparison for Atom/RSS feeds.
But sometimes changed words/content is not shown red, see
1. http://de.wikibooks.org/w/index.php?title=Esperanto&diff=374797&oldid=364671 (where it's red)
2. http://de.wikibooks.org/w/index.php?title=Esperanto&feed=rss&action=history (where no red color is used)
3. http://de.wikibooks.org/w/index.php?title=Linux-Kompendium&feed=rss&action=history (where style code is marking words red)
So, sometimes style="color: red; font-weight: bold; text-decoration: none;" is missing; instead class="diffchange diffchange-inline" is used, but does not work (at least for Thunderbird). This occurs for RSS and Atom.
