I can't reproduce it with dictionary.json, either -- but I do see
sluggishness if I go to the end of the buffer, and then lean on `C-p'.

But if I visit the file literally, then `C-p' is fast, so js-mode is
apparently having an effect on `C-p' here.  (Or perhaps it's because the
buffer is multibyte when not visiting literally and unibyte when
visiting literally.)
