This sounds great, just be careful if this command is run before the
buffer has completed loading, as you could be in the middle of a search
instead of the end.

AFAIK, with the "asynchronous" buffer loading, there's no guarantee that
point-max is the end of the search until the other thread has exited.

Again, my lisp-fu is very poor, but just a concern I see.
