The problem here is that the COMBINING GRAPHEME JOINER only affects
*enclosing* combining marks (and combining marks *following* an
enclosing one). ("Enclosing" should here be interpreted as
of general category Me, but also dependent vowels are affected
the same way.) Since combining macron/breve are not enclosing
(in either sense), this does not work: the breve (macron) only
applies to the last base letter. I vaguely suggested adding
an enclosing (in some sense) invisible combining character to
solve this: <o, CGJ, o, invisible-enclosing, combining breve>.
No character has been designated for such use, though. And I
haven't made a formal proposal yet.
