You can have four words to describe a first and last name... you can
have other alphabets, like arabian, chinese, etc... inserting accented
characters alone would make that a big, nasty regex, let alone
predicting ways you can describe first/last names.
I'm not saying that I have the _BEST_ sollution. All I'm saying is that
there are sittuations that are out of your control, and it seems to me
this might be the easiest way out, guaranteeing that there are at least
two words.
If you find a way to fit accented characters / other alphabets there
nicelly, be my guest :)
Take care.
