(nnheader-insert-file-contents FILENAME &optional VISIT BEG END REPLACE)

Like `insert-file-contents', q.v., but only reads in the file.
A buffer may be modified in several ways after reading into the buffer due
to advanced Emacs features, such as file-name-handlers, format decoding,
find-file-hooks, etc.
This function ensures that none of these modifications will take place.
