Brace expansion happens before parameter expansion (man bash,
EXPANSION). So the first "}" ends the parameter expression, and the
second "}" isn't special. The result of parameter expansion is not
subject to brace expansion.

This is correct. "a{b,c" is the default value, and "}" follows the
parameter expression.

I get "1}".
