nesting of unwind-protect and atomic-change-group

[Roland Winkler]

When combining unwind-protect and atomic-change-group I found that
putting unwind-protect outermost worked for me (i.e., an unwindform
moving point to the buffer location where the error occured was
obeyed), whereas doing it the other way round didn't work for me
(the unwindform was ignored). 

Maybe the proper ordering of unwind-protect and atomic-change-group
is obvious for experts. Nonetheless, I suggest that this should be
documented in the docstring of atomic-change-group (as it is, e.g.,
for save-excursion and save-restriction.)
