When printing a character vector, R shows a newline between the first and the second element, but not between the 2nd and the 3rd, and then again between the 3rd and the 4th.

Why is that?

Code:

> test <- c("Health: Personalised medicine and well-being.", "Personalized medicine and care, improving the hospital's care
 chain (e-health),  prevention (improving environmental and nutritional quality) .", "CCC", "BBB")
> test
