[R] Cocoa GUI: pasting in R Console yields syntax error

I faced the same problem and it took me some time to spot the origin: I 
have no clue where it can come from!( I suspect this happened when I 
moved from 1.9.0 to 2.0.0, OS X 1.3...). I know that the built in R 
editor is very handy: what I do is a "more myfile.r" on the terminal to 
check if there are weird characters and then delete then directly with 
the R editor. Not very efficient I reckon: OS X gurus may have another
