[VM] Fiddle with attachment - [Delete]

[Uday Reddy]

When you have attached a file to an outgoing message, you can right click on
it and a menu pops up.  The menu is labelled "Fiddle with attachment".

Rob F. seem to have added two functions to this menu called:

  [Delete] and
  [Delete, but keep infos]

He only implemented these functions for xemacs and the fsfemacs version is
marked as "TODO" in the source code.

So, I am wondering what these menu items do?

- the [Delete] item seems pointless because you can always delete an
attachment by killing the line.

- [Delete, but keep infos] seems to replace it with a new button that says
something like "Deleted attachment".  But what is the point of this?

Any objection if I get rid of these?

Cheers,
Uday
