bug#18340: 24.4.50; Bad UI for `find-file-literally' |

Summary: Don't show a multi-line message for prompting `y-or-n-p'
in the echo area and expect users to see it.
The UI for `find-file-literally' depends on `resize-mini-windows' being
non-nil. Not a good idea. To see how bad it can be, set
`resize-mini-windows' to nil, then visit a file, then try to visit it
using `M-x find-file-literally'. You see only this line in the echo
area, which is not even a question:
The file foo.el is already visited normally.
Huh? A user who sees that has no clue as to what is going on.
Beyond this design being incredibly ill-advised in general, it breaks
the use of a standalone minibuffer frame, for which
`resize-mini-windows' has no effect. In my code, for example, I do this,
where `'1on1-fit-minibuffer-frame' resizes the minibuffer frame to fit
its current contents:
(add-hook 'post-command-hook '1on1-fit-minibuffer-frame)
That of course has no effect during `read-key', which is what is used by
`y-or-n-p' (which is used by `find-file-literally').
`1on1-fit-minibuffer-frame' is also a command that increases the
minibuffer frame height by a line when it is repeated. It is bound
in the minibuffer to `C-o'. But of course that is ineffective for
something like `y-or-n-p', which does not use the minibuffer.
Please reimplement the multiple-line message and associated y-or-n
question for `find-file-literally', so that the message part is visible
somewhere outside of the echo area. Pop up a separate window for it,
show it in a tooltip, or show it any number of other reasonable ways.
