Thanks Martin, that indeed captures the observed behaviour in a
nutshell.

This is a valid assumption and basis of design when the completion is of
something like a command or a function name, because then the completion
list is gradually narrowed.
But in the case of completion of a file path, this assumption is not
valid. (And completing each directory name down a file path is a
perfectly normal use case.) The difference is that one is not doing a
single completion but several discrete completions.
For example, I was doing a find-file to find something in my Emacs init.
I started with `~/.em TAB' expecting a single match of ~/.emacs.d/ but
instead (of course) I got the initial completions window with .emacs and
.emacs.d in it -- a very small completions window. Then I needed a
subdirectory in ~/.emacs.d/ but couldn't remember its name at all, so I
hit TAB again and got the entire contents of emacs.d/ which is a very
long list [it seems to be jammed up full of session files for some
reason] all displayed in a buffer sized to show one line of
completion candidates.

No, not normally. When I was trying to come up with a simple
reproducible recipe I wanted an example in the emacs tree, and the
example I was able to up with was a bit contrived. (Although I don't
think it's an unlikely use case.)
