Re: nesting of unwind-protect and atomic-change-group

[Richard Stallman]

    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). 

An unwind-protect will _work_ either inside or outside
of atomic-change-group.  Whatever problem you encountered
must be more specific.  I can't guess what it might be.

Please read the Bugs section in the Emacs manual, which provides
guidelines on how to write a bug report to give us the
necessary information so we can fix the bug.
