We don't have a "template of temporary buffers".  For example, a
buffer specified by the BUFNAME arg of 'with-output-to-temp-buffer'
should not match such a template.  But I'd favor a solution that skips
all buffers whose name starts with a space as we do for 'other-buffer'
or 'unbury-buffer'.  We'd just have to document it, maybe provide an
additional argument for 'buffer-list' to not return such buffers,
decide what to do when we rename them, when they visit a file, get
killed ...
