Contrastive use of kratka and breve

[Leo Broukhis]

The difference is real and intentional, but isn't it akin to the difference
between (IIRC a discussion several years ago) the Polish/Czech acute and
the French acute - the former is more vertical? It has been decided that
there is no need for two combining acute signs.
