[Rd] Mismatch between the Rconsole file and the RGui Configuration editor

[Paulo Barata]

Dear Tomas,

I am sorry, my fault. I see now that you said R-devel 82776, not R 
patched 82776.

Yes, the problem is fixed in R-devel 82776 --- this is R Under 
development (unstable) (2022-08-30 r82776 ucrt). There is no more the 
mismatch between the Rconsole file and the GUI editor. It is all right now.

My apologies again. Thank you for your attention.

Best regards,

Paulo
