[css-ruby] Should `ruby-merge' initial value be `auto'?

Dear people concerned with CSS-Ruby,

Currently, CSS Ruby `ruby-merge` property's initial value is
`separate`.(http://www.w3.org/TR/css3-ruby/#collapsed-ruby). I would
prefer that this initial value be `auto` instead of 'separate'.

Rationale: Multiple <rb> tag within single <ruby> tag is typically
used for compound words (Jukugo). For Jukugo, the best rendering
algorithm is "Jukugo-Ruby algorithm", as its name says (see JLREQ
3.3.7). By specifying `auto` by default, the rendering engine would
display the ruby text by the best algorithm it supports (including
Jukugo-Ruby algorithm).

The current initial value, 'separate', is typically suitable if multiple
<rb>s do not constitute a compound word. In such a case, an author would
put them in different ruby segments, thus this spec is a bit
unnatural.

As of it, I would like to propose to change the initial value of
`ruby-merge' to be 'auto' instead of 'separate'.

Regards
