thank you! I just found it out myself by looking at 
https://svn.r-project.org/R-packages/trunk/Matrix/R/lmer.R.

Which brings me back to the core of my question: Where was I supposed
to find this piece of information myself. The logical place, in my
opinion, would be Section 11.3 of "An Introduction to R". Am I missing
something here? If desired, I can write a patch for R-intro.texi.

Johannes Hüsing        There is something fascinating about science. 
johannes at huesing.name  One gets such wholesale returns of conjecture 
                       from such a trifling investment of fact.
