Aah, I see; thanks.  I tried `M-x align-regexp', too, but without the
prefix, which (again) didn't really seem to do what you'd expect.  But
the doc string for that command at least mentions the prefix argument.
But makes it sound like it's more cumbersome:

---
Non-interactively (or if you specify a prefix argument), you must
enter the full regular expression, including the subexpression.
---

While instead it gives you defaults and a guided tour through the other
parameters.
