I'd think that would be pretty pointless.  You don't really lose state
if you use the "run" command.  You can easily get back to looking at
the core file by reloading it using the "core" command.

In general these "Are you sure?" type questions are un-Unixy and
rather annoying in my opinion.  They make sense if the user is about
to take an action that is going to lose state (such as loading a core
file while a program is running), but I think we shouldn't add them in
this case.
