Because "rename-file" is a relatively low-level command, which just
tells the OS to rename the file.

If you want "smart" renaming, use dired to rename files ("R" command).
It will update buffer filenames (and buffer names) accordingly.

While the latter behavior is convenient, there's certainly nothing
_wrong_ with the former -- there's no guarantee that a buffer's filename
variable refers an existing file at all (and really there can't be,
since in the general case, emacs can't keep track of what goes on in the
filesystem behind its back).
