[R-SIG-Mac] Annoying newline character saved in command history

[soeren.vogel at eawag.ch]

Dear R.app developers

Love your nice application, thank you!

When using R.app, the command history also saves newline characters  
executing commands. That is, every time when repeating commands via  
the arrow-up keystroke, another newline character is added to the  
command.

Example output from an operation:

<pre>
 > x <- seq(1:2); x
[1] 1 2
 > x <- seq(1:2); x
[1] 1 2
 >
 > x <- seq(1:2); x
[1] 1 2
 >
 >
 >
</pre>

This might be a bug since the final newline character marks the  
command execution but not a real new line. This behaviour does not  
occur when executing R via the Terminal.app.
