An even better answer is in the UPGRADE-1.6.txt document in the Asterisk source:

* The behavior of the Set application now depends upon a compatibility option,
   set in asterisk.conf.  To use the old 1.4 behavior, which allowed Set to take
   multiple key/value pairs, set app_set=1.4 in [compat] in asterisk.conf.  To
   use the new behavior, which permits variables to be set with embedded commas,
   set app_set=1.6 in [compat] in asterisk.conf.  Note that you can have both
   behaviors at the same time, if you switch to using MSet if you want the old
   behavior.
