I didn't think about it, but now that you ask, goto-line is an
interactive function that does much more than going to some line.  And
it will eventuall call forward-line, so I think it's a good idea to
call it directly. 

Otherwise, you're correct about widen, but there must be a good reason
why the user narrowed, I'd guess.

The point is that, obviously, my command lacks a good documentation
string.  Sorry about that.
