Why two functions instead of just one?
Also, I think the docstring should hint at the fact that this is meant
for cases where the before and after text share significant parts (so
there's a chance of meaningfully preserving markers). It might do that
simply be referring to `replace-buffer-contents`.

Why? AFAICT the buffer is not modified until we get to calling
replace-buffer-contents which already has (or should have) the
atomicity property.
Stefan
PS: BTW, maybe replace-buffer-contents should be changed so it
interprets a string argument as the text to use as replacement rather
than as a buffer name.
