You have a few open questions in text.texi:
> @item line-spacing
> @kindex line-spacing @r{(text property)}
> A newline can have a @code{line-spacing} text or overlay property
> that controls the height of the corresponding display line.
> @c ??? Which display line is "corresponding"?
The line ended by the newline.
If the line is continued, only the last display continuation line (the
one ended by the newline) is affected.
> @item line-height
> @kindex line-height @r{(text property)}
> A newline can have a @code{line-height} text or overlay property that
> controls the total height of the corresponding display line.
> @c ??? Which display line is "corresponding"?
> We will call the property value @var{line-height}.
Ditto.
> If @var{line-height} is 0, the newline does not contribute to the
> height of the display row; instead the height of the newline glyph is
> reduced.
> @c ??? That is not clear. Reduced how much?
To the height of the display line without the newline, i.e. to the
max height of any glyph preceding the newline.
> In that case, any @code{line-spacing} property on
> this newline is ignored. This can be used to tile small images or

> @c ??? Precisely which of these features does ``this'' mean?
line-heigth = 0
