Sorry, I just realized that my sentence was not really clear. I was not talking
about removing superfluous braces, but about adding spaces between these double braces.

dejagnu seems to be very sensitive concerning missing spaces, e.g.
"{ dg-do run}" does silently nothing, it only works if you write it as
"{ dg-do run }".
