Hi,

I encounter two cases that fill-paragraph{,-semlf} does not work as expected.

* case 1.

When I call fill-paragraph-semlf on

あいうえおあいうえおあいうえおあいうえおあいうえおあいうえおあいうえおあいうえおあいうえお。
あいうえおあいうえおあいうえおあいうえおあいうえおあいうえおあいうえおあいうえおあいうえお。

, the result is

あいうえおあいうえおあいうえおあいうえおあいうえおあいうえおあいうえお
あいうえおあいうえお。あ
いうえおあいうえおあいうえおあいうえおあいうえおあいうえおあいうえおあ
いうえおあいうえお。

I expect the last char あ on the second line is located at the beginning
of the next line.  fill-region-as-paragraph-default calls (forward-char
1)) at end, but it does not consider the sentence ends with
sentence-end-without-space?

fill-paragraph works as expected, in this case.


* case 2.

Invoke fill-paragraph-semlf on

abc def.
あいうえお。

, the result is

abc def. あいうえお。

I set sentence-end-double-space to t, then expect two spaces after
def(period).  But there is only one space.
fill-paragraph also does not work as expected.

Thanks.

Roi, could you please look into these issues?

Sorry for my late response.

Based on the description of the issue and some preliminary tests, it
seems that these bugs are not in `fill-region-as-paragraph-semlf' or
`fill-paragraph-semlf', but in the filling functions used by those
(e.g. `fill-region-as-paragraph-default').  I'll confirm that this is
the case and I'll try to provide a fix.

        Roi

Any progress with this?
