I think ‘y’ and ‘n’ are intuitive enough that they don't need a
reminder. But mentioning the more uncommon ones (‘.’ and so on) without
talking about ‘y’ and ‘n’ is weird.
So I can't see any meaningful options between the status quo and my
suggestion above.
The way I use Emacs, this would be a perfectly fine message with no risk
of resizing the mini-window:
```
Query replacing a with b: (replace ‘y’ once, ‘.’ and exit, ‘!’ all; skip to ‘n’
next, ‘^’ previous; ‘U’ undo all; ‘?’ help)
```
One idea would be to choose between the short and long messages based on
the size of the miniwindow as well as the length regexp and replacement
text.
