Comment:

 In [changeset:"32331"]:
 {{{
 #!CommitTicketReference repository="" revision="32331"
 Allow metadata to be deleted when meta_value matches 0 or '0'.

 In `delete_metadata()`, be stricter about when to ignore a falsey value of
 `$meta_value`.

 For backward compatibility, an empty string for `$meta_value` is
 equivalent to
 `null` or `false`.

 Props sc0ttkclark.
 Fixes #32224.
