Comment:

 First, I apologize for the lack of documentation of the changes. That has
 been corrected, and will appear in  the 1.63.0 release, along with some
 porting notes. You can see those docs in the develop branch now.

 As for "why did I make this change", it's because the previous interface
 was throwing away useful information - to be precise, the end of the
 matched range. If you know the length of the pattern that you are
 searching for,, *and* you have random-access iterators, then recovering
 the end of the matched range is simple and cheap.  However, that's not
 always the case.  Consider a matcher that matches against a regular
 expression.

 I wrote a blog post about this titled "sometimes you get things wrong"
