   That means that, for an unanchored pattern, if a continued match fails, it is
   not possible to try again at a new starting point. All this facility is capable
   of doing is continuing with the previous match attempt. In the previous
   example, if the second set of data is "ug23" the result is no match, even
   though there would be a match for "aug23" if the entire string were given at
   once. Depending on the application, this may or may not be what you want.
   The only way to allow for starting again at the next character is to retain the
   matched part of the subject and try a new complete match.
