I've just installed these changes:

(1) Make a new buffer local variable explicit-buffer-file-coding-system.

(2) Set it to coding-system-for-read in after-insert-file-set-coding.

(3) Set it to last-coding-system-used in basic-save-buffer-1
    after writing.

(4) In revert-buffer, bind coding-system-for-read of
    explicit-buffer-file-coding-system.
