This function doesn't use the local variables `start' and `end', and
evaluating (point-min) and (point-max) in the scope of
with-current-buffer again returns the values for the buffer just
created. Replacing `(point-min)' and `(point-max)' there by `start' and
`end', respectively, will DTRT, but then you can just use copy-to-buffer
as I showed above.
