-/* Convert tags from Xapian internal format to notmuch format.
- *
- * The function gets a TermIterator as argument and uses that iterator to find
- * all tag terms in the object. The tags are then converted to a
- * notmuch_tags_t list and returned. The function needs to allocate memory for
- * the resulting list and it uses the argument ctx as talloc context.
+/* Return the list of terms from the given iterator matching a prefix.
+ * The prefix will be stripped from the strings in the returned list.
+ * The list will be allocated using ctx as the talloc context.
