I do it the same way as Uwe does it, and if I work on a multi-file
document, I call `C-c C-n' (Save buffer _including_ style
information). I think one has to do that once in each file of the
multi-file document.

,----[ C-h k C-c C-n ]

Yes, this is not optimal, but I don't start new multi-file projects
all the time and it is better than having ./auto directories spread
all over my home directory.
