I replied separately to the bug report you filed, but I reply here as well, to
help others who might be interested.

My suggestion above was incomplete. I should have suggested to first, before
reading NEWS, look at the doc for the key you're using. `C-h k C-h i' says this
as part of the description of command `info':

"In interactive use, a non-numeric prefix argument directs
this command to read a file name from the minibuffer.
A numeric prefix argument selects an Info buffer with the prefix number
appended to the Info buffer name."

This means:

* `C-u C-h i' (using a non-numeric prefix arg) does what you were looking for:
prompts for the Info file to use.

* `M-2 C-h i' (using a numeric prefix arg) opens Info with the buffer named
`*info*<2>'.
