Tena koe ?rep states that each is a non-negative integer. Note, integer not a vector.
Thus, rep(1:3, each=c(2,1,2)) only uses the first element in each and is equivalent to rep(1:3, each=2). One could argue there should be a warning (as there is for some functions is similar situations), but I don't see that it is a bug or undocumented (although the documentation is subtle). HTH ....
