The doc-string for `w3m-copy-buffer' might have had to mention
as follows:

  If EMPTY is non-nil, an empty buffer is created, but with the current
- buffer's history and settings.

That behavior is necessary to render something in the new buffer
before displaying it.  So,

Hmm, no such critical change was made in `w3m-copy-buffer' for
years AFAICT.
