Turns out "zle auto-suffix-retain" already serves this purpose.
This is tricky because widgets created with "zle -C" start directly in
completion context, which means that "zle" generates an error; i.e., if
we naively stick this into _generic:
_generic:zle:1: widgets can only be called when ZLE is active
(The error should probably be more specific, since a completion widget is
merely the wrong *kind* of widget.)
The solution is to make a normal widget for auto-suffix-retain, then invoke
the completion widget with "zle the-widget -w". This seems a bit more work
than should be necessary, but see example below.

Just as-is, this works as you desire if the initial directory completion
is not ambiguous, but cycles if there are multiple possible matches in
the current menu.
} I would like ^N after TAB to start completion over (even if this was
} originally a ^N completion), but TAB after ^N to continue the same
} completion.
The following uses the normal-widget-calls-completion trick. There may
be a better name for it.
-- 8< --
# Replaces bindkey in the above, otherwise all the same
complete-most-recent-file () {
[[ $LASTWIDGET != $WIDGET ]] && zle auto-suffix-retain
zle most-recent-file -w
}
zle -N complete-most-recent-file
bindkey "^N" complete-most-recent-file
-- 8< --
If we're OK with this, Oliver's patch can remain, but it's possible that
there are other user-defined widgets that will start behaving unexpectedly.
