Hi,

The buffer is an implementation detail for the member of
eldoc-display-functions that writes to the echo area,
so it's hard to do away with.  However, it should be reasonably
easy to "hide it", as Xu suggests, by prefixing its name with a
space. The the eldoc-display-in-eldoc-buffer display function
just renames it to not have that space, promoting it
to visible.

Thanks for CC'ing me,
João
