Subject: [PATCH] (mime-edit-normalize-body): Use `mime-charset-type-list'
 directly; abolish local variable
 `mime-edit-charset-default-encoding-alist' and function
 `mime-make-charset-default-encoding-alist'.
 (mime-edit-toggle-transfer-level): Don't set up
 `mime-edit-charset-default-encoding-alist'.
