To handle all situations correctly is impossible.  You can't properly
match nested constructs like balanced parens/braces using regular
expressions.  For that, you'd need an actual parser.

But you can at least allow a fixed number of balanced braces, and I've
just done that in order to allow one level of nested {...} in mandatory
arguments.  (We already allowed for one level of nested brackets in an
optional argument.)

I'll make a new ELPA release.

Thanks for the report and Bye,
