I didn't express it well. That language solves the braces problem by 
using a different scheme (that doesn't use braces):

A68: if a;b then c;d;e elif f then g elif h then i;j else k fi

C:   if (a,b) {c;d;e;} else if (f) g; else if (h) {i;j;} else k;

- C needs 3 grouping methods for serially-evaluated elements:
   (), {} and nothing, compared with one (and uses either "," as
   [effective] separator or ";" as terminator).

- C allows single elements to either be inside {} or not, adding
   variability to code (and introducing the problems that have been
   discussed when code subsequently is edited). Elements that are
   conditional expressions must use ().

- C leaves itself open to the dangling else problem

- If C closes an if-statement with }, then it has the problem that
   it can get mixed up with a closing brace from another kind of
   statement (not possible using 'fi' or 'end if').

- There are probably more placement styles for { and } than are
   possible with the A68 scheme; yet more variability in code.

But apart from all that, there's not much in it...
