v2.27:

  * datatool-base:

   - reverted \dtl@insertinto to pre v2.26. (The bug fixes
     in v2.26 caused backward-compatibility issues, which

     are how \dtl@sortlist and \dtl@insertinto ought to
     behave but don't). The internal commands are left for
     backward compatibility. The user commands should be
     used for the correct function. (Added new section in
     the user manual documenting these new commands.)
