IMO, these are bugs, not just documentation issues.

I think we should make latin-prefix be consistent with latin-postfix.
Each one of the above is correct in the latter, AFAICT, so we should
just fix the problems in latin-prefix.  E.g., ~a should produce both ã
and ă, ~c should produce č, and ġ should be produced by .g.  I see no
reason to have these two behave inconsistently; do you?
