Insert half-space in abbreviations

The German (and probably other languages’) typographical rules demand that a half-space is used in abbreviations. E. g., the space between the period after “E” should be a half-space. In HTML, this could be rendered as unicode THIN SPACE (#8201). As this is a not non-breaking character, the whole abbreviation should optionally be wrapped with white-space:nowrap

I am building a input filter for a customer right now that adds the above refinements to his drupal site. Is someone working on implementing this within the Typogrify project? If not, I can offer a patch as soon as I’m done here.
