+ * replace.el (query-replace-from-to-separator): Turn defvar into
+ defcustom. Wrap char-displayable-p in ignore-errors because an
+ attempt to autoload char-displayable-p fails during pre-loading.
+ Move (propertize "\0" ... 'separator t) out of customizable part
+ to query-replace-read-from.
+ (query-replace-read-from): Call custom-reevaluate-setting on
+ query-replace-from-to-separator to reevaluate the separator
+ depending on the return value of char-displayable-p.
