bug#293: 23.0.60; Combining diacritical marks are non-combining

[Torsten Bronger]

When using Unicode's combining diacritical marks, the accents are
printed to the right of the character instead of on top of it, for example
ẍ̇ or ẍ.  This used to work in Emacs properly (al least for some
character/accent combinations, and in particular for the examples).
