well, generally speaking, it's because whenever this topic has come up
before, it's someone suggesting that lynx make some special case for
buttons with type=button (a script).

However, you may be talking about a case with a correctly formed page.
For instance, to refresh my memory, I looked at the dtd and see that
if no type is given, the button should be a "submit".  Something like
this would have been a useful patch:
