It fails because you are using a non-standard file name
"changelog", and not the default "ChangeLog".  You can customize
`change-log-default-name' to "changelog" then isearch will wrap
to the beginning instead of trying to wrap to a non-existent "ChangeLog".

I'm not sure whether we should deduce change-log-name from the
file name of the current buffer (removing possible suffixes
like ".10" from "changelog.10").
