Using CL-PPCRE sounds interesting. It would be a useful add-on package for
other purposes also. I looked at the code and it's not too big,
a few hundred kbytes.
If build_index.lisp + CL-PPCRE solves the problems with
the German translation, I'm willing to include it in the 5.23 release.
For the record I see that CL-PPCRE is BSD-licensed.
