Anyway I realized there are many possibilities that will cause
default-directory to be "~/".  For such a circumstance, your
patch is not necessarily effective since emacs-w3m is far to
supporting the buffer: scheme fully.  The typical case is to
try to preview an html source that is only in an Emacs buffer,
not associated to a file.  It won't be easy to improve, but I
think it is a necessary feature since this is *emacs* -w3m.
Isn't there any developer who has an interest in it?

Indeed. :)

Otherwise, change `w3m-buffer' so as to display a preview in the
other buffer (i.e. one of tabs) by default.  It requires emacs-w3m
to support the buffer: scheme properly, I believe.  Moreover
`w3m-region' should work as well.  So, maybe the buffer: scheme
needs to have a means to specify the start/end positions like:

buffer://BufferName(start,end)

Where (start,end) is optional.
