Hmm, ok.

`line-number-mode' because I really meant `hl-line-mode': that would
have shown a visible effect, namely that cursor is located on a line
different from the one where it appears.  But yes, it's unrelated to the
recipe.

Second question: for the recipe, it's not relevant indeed, but it is in
Magit, because in Magit, they have set line-move-visual -> nil.  That
fixes the problem, but it fails to do so (only) when goal-column -> nil.

Yes!

But in Magit, it _does_ help (i.e. move the cursor out of the invisible
text).  In my recipe, which is modeled after the Magit case, it doesn't.

Ok, will do.  Thanks for investing time here.
