When I'm composing a message in message-mode I sometimes want to remove a recipient from a long list of recipients on the To: line. It seems that there is no semantic kill command that would delete a complete recipient.
I could zap to the next delimiter, I suppose, but the different formats available for recipients and their display names makes this a lot harder. When on a To:, Cc: or Bcc: line, I really don't need to be able to delete words or sentences or s-expressions, I just need to be able to remove a recipient as a syntactic unit.
How can I easily augment kill-sexp to remove a recipient (i.e. name and email address in the various common formats) when I'm on a recipient line?
