+ "Return coding system for the \"control\" file in a deb.
+This function is for use from `file-coding-system-alist'.
+ARG-LIST is arguments passed to `find-operation-coding-system'.
+The only operation handled here is `insert-file-contents' with a
+buffer filename \".deb-INFO!./control\", for which the return is
+'utf-8, and for anything else the return is nil (letting
+`find-operation-coding-system' try other things).
+This is done as a function because the filename passed to
+find-operation-coding-system by tar-mode is merely the archive
+member \"./control\". By looking at the buffer-file-name we can
+tell if it's from a deb.
+Note: This only works in emacs22, in emacs21 or xemacs21 tar-mode
+does something a bit different and doesn't reach here (and
+there's no buffer passed to coding system functions)."
