I don't know if it's documented but it makes sense if you consider
these examples:

    % print "${foo:-bar}baz"
    barbaz
    % print "${foo:-bar}baz}"
    barbaz}
    % print "${foo:-{bar}baz}"
    {barbaz}

"{" isn't special on its own unless it is preceded by "$". Thus, the
first "}" encountered after "${" marks the end of the expansion.

Roman.
