[R-SIG-Mac] Re: R Aqua 2.0.1 interface: what happened?!

Hi RenE,

Thanks for your efforts to pinpoint these issues.

Below set of issues have now been fixed (and will be incorporated into 
Simon's
nightly build 877):

and

It makes no difference if files passed on the command line are to be 
opened in a window or sourced (this option seems not to have any 
effect, BTW). The same command has the expected effect when R.app is 
already running (with the exception of the aforementioned option).

Feedback, as always, is more than welcome. Before adding some features 
to the editor (line
numbers!), I really would like the existing code to be solid.

The font issue on RQuartz is more complicated and a new topic for me. 
I'll take a look early
next year. Once I understand it better, I will enable the font 
selection in the preferences
panel.
