Recognising 1st and last name in dialog

If my character name contains a 1st and last name, or more than two, character dialog should pick out the first and/or last as appropriate. Or maybe just have two fields for the character name.

I just made a character called "Lourthag Bloodjaw" and it looked ridiculous when Imoen addressed me by my full name. And imagine someone in a panic referring to me by the name of Johannes Chrysostomus Wolfgangus Theophilus Mozart...
Also, unless otherwise stated, any idea I suggest is configurable and the old behaviour is obtainable (Though unneeded in this case--see above). Maybe I should state it every time though to ward off the 'disagrees'...
