Done with the `scroll-command' property.

Unfortunately, the definition of a scroll command used
by `isearch-allow-scroll' is too broad: it can be a command
that scrolls the window, acts on the other window or changes
the window layout.  I'm not sure if it would be good for
`scroll-preserve-screen-position' to put the `scroll-command' property
on all these commands that currently have the `isearch-scroll' property,
or whether some users might want to remove the `isearch-scroll' property
from some real scroll commands.
