    The value of parameter is substituted. The braces are
    required when parameter is a positional parameter
    with more than one digit, or when parameter is followed
    by a character which is not to be interpreted as part of
    its name.

I think that's Posix standard. Do you really need that extended
expansion, or are you just using variable substitution?

Note, I haven't actually looked at the code.
