AFAIK, there is not. This is why reload_buffer is in bufutils.sl.

Is there something you want to change in the code or do you just want to
skip the dependency on bufutils.

you could try

- 	buffer_keystring ("yes\r");	% yes = reload
+       % reset the changed-on-disk flag to prevent asking
+       setbuf_info(file, dir, name, flags & ~0x004);
> 	() = find_file (file);

but maybe this will not load the new version any more :-(
(BTW, the version in http://jedmodes.sf.net/mode/bufutils/ works without
simulating keystrokes.)
