VcRefactoring: Merged [3324:3538/trunk] (painless!)

Some minor cleanup in the font formatting code, suggested by Bjorn Swift. Thanks!

In the !OutlineFormatter, the anchor of headings must always be computed on the full wikified heading, as this is what will be used by the normal Formatter when rendering heading ids. Fixes a problem observed with long headings in the TracFaq.
