relinkBacklinks(sourceType: "dump_comment" | "comment",sourceId: string,fromDumpId: string,text: string): void
Replaces the backlinks from one text, a dump's note (dump_comment) or one
of its comments (comment), with the links its current text holds. A link
counts when it is a dump's page on this site (/@owner/dumps/<slug>), or
when it is the URL a dump was posted with, compared by canonicalizeUrl as
reposts are. The dump and
comment services call it on every save, and with an empty text when a
comment is deleted. Clients are told of the dumps it links or no longer
links, as dump_related_changed.
