Description:
The exist status of mysql_upgrade does not give a distinct codes to programmatically identify failure causes.

How to repeat:
Run mysql_upgrade twice in a row

matt@silo:/data/mysql/sandbox/7.0.13$ mysql_upgrade
[...]
Running 'mysql_fix_privilege_tables'...
OK
matt@silo:/data/mysql/sandbox/7.0.13$ echo $?
0
matt@silo:/data/mysql/sandbox/7.0.13$ mysql_upgrade 
Looking for 'mysql' as: mysql
Looking for 'mysqlcheck' as: mysqlcheck
This installation of MySQL is already upgraded to 5.1.41-ndb-7.0.13, use --force if you still need to run mysql_upgrade
matt@silo:/data/mysql/sandbox/7.0.13$ echo $?
1

Suggested fix:
Change the exit status of mysql_upgrade from re-attempt after successful completed upgrade to 2.

Patch to follow.
