Not just countries, but also states (different shields per state, for 
instance). Granted: same thing really.

A little birdie once told me of a trick used by a certain map maker. 
Split the border-crossing road twice, so there is only a short section 
that actually crosses the border; probably less than 10 meters. Assign 
one of the styles to that short section, either randomly or by length or 
any other means. Because these sections are so short, it's not 
noticeable on a map, and you don't have "style bleed".
