Hi,

If I am reading the spec right, when the hanging-punctuation
property is set to force-end, and text-align is left in ltr text
or right in rtl text, if effectively causes a single line to be
justified.

The spec does not say if this single line justification
is expected to follow the justification method determined
by text-justify or not. I think it should follow text-justify.

If text-align is justify, my understanding is that
hanging-punctuation:force-end and hanging-punctuation:allow-end would give
the same result. Is that correct?

If text-align is right in ltr text or left in rtl text, I am not
entirely sure what the expected behavior is. In the following
examples, the '|' character marks where the padding starts.

text-align:right; hanging-punctuation:none;
|      some words.|

text-align:right; hanging-punctuation:force-end;text-justify:inter-word;
|       some words|.
|      some  words|.
|some        words|.
|s o m e w o r d s|.

The first interpretation shifts the line.
The second uses justification, but without putting any text further left
than you would have without hanging-punctuation:force-end;
The third justifies using the whole line.
The fourth justifies using the whole line, without respecting
justify:inter-word;

If text-align is center or <string>, I am even more at loss when trying
to imagine what the expected behavior is.

An alternative to all this would be that force-end never does anything
unless text-align is justify, and that the example give in the spec
assumes text-align:justify.
