Nah.  There is no interactive spec in the `w3m-db-history' function (i.e., there is no operand in
the (interactive) line), so `start' and `size' will be nil if it is called interactively, and a user
should always be prompted for them.  You wrote in the comment:

(t ; called interactively; possibly indirectly

I imagined that the indirect case would probably be to call this function from a custom ELisp
command that specifies `start' and/or `size' by something like prompting a user.  In that case, this
function should honor those arguments rather than prompting a user for them again, I thought.

To be continued
