If you are not satisfied with the message as it is, you can edit it
using a text editor specified either by EDITOR or by
VISUAL environment variables. The ‘~e’ uses the former,
and ‘~v’ uses the latter.
By default both escapes allow you to edit only the body of the
message. However, if the editheaders variable is set,
mail will load into the editor the complete text of
the message with headers included, thus allowing you to change
the headers as well.
