First paragraph may be correct -- but (I suspect) only because, for 
whatever reason, "that's the way Mathematica does it".  I'm skeptical 
that Mathematica *has* to do it that way -- that is, has to break a 
single curve into some number of smaller sub-segments -- for any major 
technical reason; and it would be nicer if it didn't do it that way.

Are there technical reasons (maximum number of points per Line[], or 
something like that) why Mathematica has to do it this way?

Also, if you Select first segment A, then segment B, of a segmented 
curve of this type after transferring it from Mathematica to Illustrator, the 
curve appears continuous.  Does this mean that the final point of 
segment A and the initial point of segment B are the same? -- or just 
very close to each other?  Or does the EPS file somehow contain enough 
data that Illustrastor knows how to fill in the gap between last A and 
first B points?
