[R-sig-ME] generalized linear mixed-effects model and lmer, lme

Perhaps the example currently given is not the clearest one that could
appear in the ?lmer helpfile. I would suggest either replacing it with
a more elementary example, or else adding a comment line indicating
that the only difference lies in the correlation structure.

What about:
Example 1: lmer(Reaction ~ Days + (1 | Subject), sleepstudy))
Example 2: lmer(Reaction ~ Days + (Days | Subject), sleepstudy))

People looking at the helpfile might find that one more helpful.
There's something elegant about the current example, but it certainly
threw me too, until I inspected the output carefully.
