bug#2228: 23.0.90; rmail-cease-edit ignores changes to the message headers

[Richard M Stallman]

    I think that editing a message should present the message with headers
    expanded.

I think that editing the pruned headers is an important feature.  The
full headers are too long and inconvenient.

As it is now, you get the choice.  If you display the full headers and
then edit, then you get to edit the full headers.
