Hi, all--
I was playing around with the Packages menu in the Windows RGui, and
noticed that when I chose Select repositories and clicked Cancel,
instead of being returned to the R prompt I was faced with a text
version of the menu. I think the text menu should only appear
if graphics=FALSE, and should explicitly say how to cancel, as well.
The following changes make that happen:
