Hi:

Sorry to bother with this.

Fixing the issue 36858 in text mode I found that the
extend_face_to_end_of_line uses the same face for the last char in the
line.

This is useful to extend selection face the whole line, but this created
a difference with gui emacs when the last face was underlined or
overlined because in tui the underline is extended for the entire line.

To fix this I need to create a new face to extend until the end of the
line that has the same properties than it->face_id except that the
underline and overline properties will be disabled.

I can produce the desired effect doing:

```Lisp
(defface my_new_face
  '((t :weight normal :slant normal
       :underline nil :overline nil :strike-through nil
       :box nil :inverse-video nil :stipple nil)))
```

```C
DEFSYM (my_new_face, "my-new-face");

it->face_id = merge_faces (it->w, my-new-face, 0, it->face_id)
```

But this seems very dirty.

How can I produce the same effect in the right way? (I mean create a new
face_id based on it->face_id but with :underline nil :overline
nil... etc?) And only with C code.

Any help, suggestion?
Thanks in advance,
Ergus

Inasmuch as Ergus has recently expressed a desire to work on face extensions, I thought it would be helpful to bring to everyone's attention a couple of recent threads where a user is attempting to workaround (using Lisp) a background face that gets extended when folding source code blocks in org-mode:

Thanks,

Keith
