Recently, R.app (2.7.2 on Leopard 10.5.4) has begun to append newlines

reproduced again. I've been running 2.7.2 since it came out but this
behaviour is recent (past couple of days):

Have you checked the R.app preferences.
I think that you want to have Cleanup history entries
checked under the startup preferences.
