Korean: space check in names about scriptshifter

Never mind. I misinterpreted the return value of StringInStr.

Originally there has to be only one space in personal names: always between last name and first name.
There is no middle name. Also note that women keep their family names, and marriage does not involve a change of last name.
Children used to get only paternal last name.
Recently, however, some people started use both paternal and maternal last names at the same time, although it is not officially accepted. This is the only case when we have two spaces in personal names.
I wanted to deal with this two-space cases.
