Thanks.  Not only `w3m-browse-url' but also at least the following
commands will need to run it, too:

w3m-view-parent-page
w3m-scroll-up-or-next-url
w3m-scroll-down-or-previous-url
w3m-gohome
w3m-find-file
w3m-db-history
w3m-history

Maybe it's better to modify the condition that decides whether
`w3m-goto-url' runs `w3m-history-store-position' (currently it
runs it only when called interactively).  But in my experience,
it likely causes another bug.

It should be called in the w3m-mode buffer.  So, `w3m-browse-url'
should go to the w3m-mode buffer, if any, in advance.
I'm going to work on this...
