These aren't "binary files", so setting find-file-literally may have
undesired effects.  E.g. the coding cookie will be ignored upon save,
even though such files might like to use them.  Those will also like to
obey require-final-newline, BTW.

So I suggest to set find-file-literally only in the case where
buffer-file-coding-system is `no-conversion'.
