That is a general problem in the indentation of function arguments,
not just when they have nested code blocks. I deal with it by
inserting a line break after the open parenthesis, treating it much
like a brace block opener:

    some_really_long_function_identifier (
        bar, {
            zot;
        },
        baz);

The problem really lies in the indentation of arglist-cont-nonempty,
which is usually set to c-lineup-arglist. It ought to be possible to
get approximately the identation you want in a consistent manner by
setting arglist-cont-nonempty to + instead. Currently it isn't, since
statement-block-intro and block-close aren't stacked with
arglist-cont-nonempty. I'll fix that.
