Vi isn't nasty enough, so user looses lines

[Tanner Andrews]

] description of user deleting lines, saving part of file, doing
] normal exit (":wq") from vi to save whole file, not getting warning.

It sounds like a normal job of work being done on a file.  Perhaps
part of a program being ripped out, as it the code it was there to
debug turned out not to contain the problem; the total job being
finished in the normal manner.

What kind of warning should the user get?  Is this warning to be
applied to all work done in the editor?  Maybe I need to eat more
of those fine powdermilk biscuits, but do we need a warning like
(reverse-video on the line below -- add flashing and bells too)
"You are about to save your changes -- use wq! to really do it"?
