Hi there,
one last patch before christmas: I have a file like this (well, I have
many of them, this is just one example)

  template <int dim>
  class X {};

  template <>
  class X<1> {};
(i.e. X has a general template, but whenever I want a X<1>, then the
explicitely specialized one is taken).

I would like the explicit template parameter to show up in the class name,
i.e. one class X, another class X<1>. The following patch (today using -u)
does this:

This thing has one unfortunate drawback: for the class X<1>, a similar
file is created, i.e. one would have to escape file names properly. I have
not done this yet, but I can do it if you want me to, Taj.

Ah, and I still have one more patch in my Santa Claus bag: the foot line
usually fails for me (my user name is not printed, only 
  'generated by @atlas ...'
The reason is that we do not have whoami installed. But we have 'who am
i', so this might or might not be a good patch:

I wish everyone a pleasant time over the next days. Heidelberg is covered
under approx. 30cm of snow, so that makes it feel very much like
Christmas. I image that for most of you others on this list (Marcin,
Rainer, ...) things are similar -- and Taj, just enjoy a handful of white
sand instead ;-)
