I feel something wrong with fill functions.

For example, when I hit M-q on the following line,

aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa.  aaaaaaa aaaaaaa.  

it becomes...

aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa.
aaaaaaa aaaaaaa.

Well, quite okay.  Hit M-q again....

aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa
aaaaaaa. aaaaaaa aaaaaaa.

Oops.  It seems that a period just before newline isn't treated as the
end of a sentence.  Is it supposed behavior?

Next example.  When I hit C-u M-q (fill with full justification) on
the following line,

aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa aaaaaaa
aaaaaaa. aaaaaaa aaaaaaa.

it becomes...

aaaaaaa    aaaaaaa   aaaaaaa    aaaaaaa   aaaaaaa    aaaaaaa   aaaaaaa
aaaaaaa. aaaaaaa aaaaaaa.

Hmm, I think it is not balanced well, but maybe it is okay.  Then I
hit M-q (no prefix) again but it doesn't change.

Info page says:

   A numeric argument to `M-g' or `M-q' causes it to "justify" the text
as well as filling it.  Extra spaces are inserted to make the right
margin line up exactly at the fill column.  To remove the extra spaces,
use `M-q' or `M-g' with no argument.

but actually it doesn't work.

While I'm writing this mail, I noticed that spacing between words
varied each time I filled the lines with justification.  Sometimes it
becomes quite unbalanced like:

aaaaaaa     aaaaaaa   aaaaaaa aaaaaaa      aaaaaaa  aaaaaaa    aaaaaaa
aaaaaaa. aaaaaaa aaaaaaa.

Is it okay?

Also I feel something wrong with filling Japanese sentenses.  Fill
functions tend to fold sentenses where they shouldn't.  For example,
they tend to remain "$B!V(B" (open bracket) at the end of line, and move
"$B!$(B" (comma) to the beginning of line.  Is there something reversed ?

I tried them on XEmacs 20.1-b15 with Mule support.
