So, as one makes the window wider, instead of using the additional
space to display more of the file name, we will use it to display more
of the buffer name?  Even if none of the buffer names is truncated?

Not to me: if we could find a way to show the buffers in a way that
makes the differences between similar names apparent, maybe there
wouldn't be a need to make the buffer name wider.  But it's fine with
me not to handle the latter (and harder) issue for now.
