 When trying to update myth from 0.21, the pre-update dtabase check fails
 if the "people" table contains entries with names that differ only at
 character positions > 41.
 reason is in mythtv/libs/libmythtv/dbcheck.cpp 3593:

 the command generated for testing the table for unique utf8 entries is
 "ALTER TABLE temp_people   ADD UNIQUE INDEX verify_unique ( name(41) );".
 thus only the first 41 characters are indexed and failures occur if two
 entries only differ past char 41.
 removal of the "(41)" should fix this problem.
