This tend to be very complex for user. And definitely not a good idea to
include country domains in this list, lots of countries here around.
One that I proposed was to add a boolean like
URL_DOMAIN_NOGUESS_TWO_LETTER_SUFFIXES:TRUE
Probably, we should disable any domain guessing by default
except for few strongly suggested suffixes like ".com"
BTW, we can set an empty guess by URL_DOMAIN_SUFFIXES:.
