Currently the sql_safe_updates variable cannot be set in my.cnf.

If you set it anyhow, mysql throws the following error on restart:
"unknown variable 'sql_safe_updates=1'"

I find sql_safe_updates a very useful safety net.

One would need to add "safe-updates" command to my.cnf to turn it on.
This command sets the following variables as well:

I think sql_safe_updates is a unique variable by itself and has a great potential helping many developers. So in IMHO, we should be able to set it by itself in my.cnf without having to set two other variables.

How to repeat:
You cannot set sql_safe_updates in my.cnf

Verified with 5.5.28 also:

120825 18:04:31 [ERROR] /Users/openxs/dbs/5.5/bin/mysqld: unknown variable 'sql-safe-updates=1'

It would be nice to be able to set this variable in my.cnf or as command line option.
