Eh? Last I used mailx, the difference between r and R is that one replies
to the sender only and one replies to everyone named in Cc:s as well as
the sender. It always used the From_ return route. To reply to the
address given in a From: line I'd have to edit the address manually.
Of course, mailx has many more problems than that, and I was happy to
punt it..
