--------------------------------------

             Summary: [C++] Option for match_substring* to return NULL on NULL 
input
                 Key: ARROW-16047
                 URL: https://issues.apache.org/jira/browse/ARROW-16047
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Jonathan Keane


We implemented this in the R bindings as a wrapper in ARROW-16007 (and there's 
even a start of an implementation at 
https://github.com/apache/arrow/commit/f445450aeeaeee96b9eeba5549c36c5229f18a8f 
provided by [~ateucher] )

This is should be done for {{match_substring}} and {{match_substring_regex}} 
(any others?)
