X-Symbol's decode function sometimes[1] does pay attention to
`buffer-file-coding-system'.  (A hypothetical question became real...)

It would be excellent if Emacs could be patched such that
`after-insert-file-set-buffer-file-coding-system' is called directly
from within Finsert_file_contents before calling Qformat_decode (instead
of adding this function to `after-insert-file-functions').

[1] with unique decoding and 8bit char use in the file: then \oe would
not be decoded with a latin9 coding system, but it would be decoded with
a latin1 coding system.
