Actually, even in scripts like Latin, it should be "start of end of a
connected glyph cluster" and not "start or end of a word".  

If the miniscule folling a majuscule does not connect to the previous
glyph then it should use its initial form.

At least conceptually.

Making it work does seem to be left as an exercise for the reader^W,
err, writer(?). ☺
