Ikumi Keita kindly wrote to me how fill-space was used in
Emacs.  For developer and future help, I'll try to summarize
his mail.

[summary]

We, Japanese, sometimes mix Japanese character and Latin
character.  There exists two manner to mix them; (1) insert
space between them.  (2) not insert space between them.

ex.
 (1)  ...<j> <l>...
 (2)  ...<j><l>...

<j> and <l> mean characters of Japanese and Latin,
respectively.

When a line was broken just at `space' between <j> and <l>,
there left no information that there was space between <j> and
<l>; in other words, Emacs does not know which manner the
writer used in this line.

A text property 'fill-space tell Emacs if there was `space'
between <j> and <l>, when break point is changed.


I conclude that 'fill-space is useful in Emacs 21 :)
