--replicate-rewrite-db=from_name->to_name does not work if from_name is 1 character long.

Error message returned is:
Bad syntax in replicate-rewrite-db - empty FROM db!

How to repeat:
doesn't work:

mysqld --replicate-rewrite-db="a->b"


mysqld --replicate-rewrite-db="aa->bb"

Suggested fix:
fix handle_one_option() ?

Documented in the 5.6.4 changelog as follows:

        --replicate-rewrite-db=from_name->to_name did not work correctly 
        when the name of the source database (from_name) consisted of 
        only a single character.
