Re: Question about align-to behaviour with wrap-mode

Thanks Eli for explaining.

This is what I see with this example on my Emacs 28.2 (assume window width is 
50):

,----
| EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
|                                         After
`----

So the text is "correctly" aligned to (- right 10) on the second line. Are you 
seeing something different?

The only problem I see is that when the word is broken and word-wrap is off 
then I get

,----
| EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE Af
| ter                                      
`----

while if word wrap is on I get

,----
| EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
| After                                      
`----

I see. Do you mean that I should write a hook to update the alignment of 
"After" as more text is inserted before it (to calculate the alignment column 
taking the continuation lines into considerations)?
Or is there a way to have `align-to` be calculated from a function?
