Message:
Fixed some buffer overruns in the "reply" command.
When repying to "all" on a message that begins with "CC:" (eg, sent
         with "zwrite -C", the reply line will be constructed
         from the sender and the usernames on the CC: line
         of the message being replied to.
There is no such thing as C-R, so left C-r as it is but added:
         M-r --- edit reply to all
         M-R --- edit reply to sender
