Hi,

I attached a patch fixing the problem Ulrike Fischer described in https://tug.org/pipermail/luatex/2019-April/007127.html and https://tug.org/pipermail/luatex/2017-November/006641.html :
\shapemode=2 and \shapemode=3 should mirror the parshape, but until now this has only been done for the final entry in the parshape list, leading to inconsistant behaviour.
The fix seems easy: Add `swap_parshape_indent` to ext_post_line_break in the same way as in ext_do_line_break.

A reproducing example in plain TeX can be found in Ulrike's mails linked above.

Thank you very much for the patch, I will see i asap.

Given that practically TeXLive 2019 is done

https://tug.org/pipermail/tex-live/2019-April/043549.html

this weekend I will sync the texlive repo with the luatex repo and make the tags/1.10

Then I will see the patches.

I think than now patch adoptions will be a bit slower, because we have to carefully consider

the side effects on the formats like context, lualatex and on the packages using lua.
