24.5; can not set line height |
Date: |
Mon, 20 Jun 2016 11:15:11 +0900 |
`line-height' property is effective only at the newlines,
so there are no chances to set line height
(1) when the line is wrapped
(2) when the line is truncated
(3) when the line is at the bottom of a buffer
and not terminated by newline

Yes, and its documentation also refers to a "display line".

What do you mean by "partial buffer contents"?

Such an extension could be added.

It's documented, sort of, by saying that only the visible content
determines the line height in this case. But I made that more
explicit.

Actually, it doesn't override, but compared, and the largest value
used instead.
I fixed these inaccuracies, and I'm marking the bug done.
Thanks.
