This function creates a completion table that behaves like the existing
-completion table @var{table}, except with additional metadata, specified
-by the completion metadata alist @var{metadata}. If @var{table} already
-provides completion metadata, that metadata is merged with
-@var{metadata}, giving precedence to @var{metadata} in case an entry
-appears both.
+completion table @var{table}, except that the new table uses the alist
+@var{metadata} as its completion metadata.
