Since changing the coding system changes the modified status of the
buffer (and changes the format in which the file is saved), it
definitely makes sense to record the change in the undo history (both
when it is done automatically, and when done by the user via C-x C-m f).

But maybe it could delay the actual change in the coding system until
it has finished inserting the text, display the buffer using the
current coding system (which may of course look really messy) - and
then ask the user whether he wants to change the coding system of the
buffer or keep what he sees.
