            <title>[SERVER-7668] Split chunks on tag ranges</title>

                    <description>&lt;p&gt;When moving chunks with ranges see if they reside on a tagged range and split at that value so chunks don&apos;t span tagged ranges.&lt;/p&gt;</description>

&lt;p&gt;Message: removing incorrect section&lt;/p&gt;

&lt;p&gt;This hasn&apos;t been the case since 2.2 - see &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-7668&quot; title=&quot;Split chunks on tag ranges&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-7668&quot;&gt;&lt;del&gt;SERVER-7668&lt;/del&gt;&lt;/a&gt; which fixed it for 2.3.2.&lt;/p&gt;

&lt;p&gt;This removes the complicated modifiedRangeBound method in&lt;br/&gt;

toKeyFormat method. The latter has been split into two functions,&lt;br/&gt;
toKeyFormat and inferKeyPattern, which have more intuitive behavior.&lt;br/&gt;
