[R] Rgui.exe fix for "console not found" buffer overflow problem

[Jesse Albert Canchola]

Hi Duncan and Gabor,

Many thanks for your responses*.  Right, the --vanilla option did not 
work, as you mention and I had very few clues to go on.  Your fix 
mentioned below should do the trick.

Regards and have a great day,
Jesse A. Canchola

* My apologies for the redundant second post.  It "seemed" that my company 
blocked my initial post (the server thought it was a spoof) so I sent it 
via my gmail account not realizing it had actually gone through.  Ignore 
this second post please.

Right.  This would be more obvious if I'd followed the standard Windows
convention and labelled it as "Load..." instead of "Load".  The dots
indicate that you'll get another dialog and opportunity to cancel.  I'll
change that.
