ndaries" above describes an issue that arises if the pattern ends with
\b or \B. Another kind of difference may occur when there are multiple
matching possibilities, because (for PCRE2_PARTIAL_SOFT) a partial match result
is given only when there are no completed matches. This means that as soon as
the shortest match has been found, continuation to a new subject segment is no
longer possible. Consider this <b>pcre2test</b> example:
<pre>
    re&#62; /dog(sbody)?/
  data&#62; dogsb\=ps
   0: dog
