I think this is a good idea: this footer will be still displayed
but not copied or saved.

But please don't use such overlays for compilation buffers - they are not
like diff output.  After saving and later visiting the old compilation
output it is useful to see the overall status of the compilation at the
end of the saved output file.  Also it is useful to see how long the full
compilation took time (by subtracting times at the beginning and the end
of compilation) to make estimation how long the next compilation will
take time.  However, nothing like this is necessary for diff output
which I think should have no additional text appended in the saved file.
