I think that's probably intended to handle cases like compiling C++ with -ffunction-sections.  In that case you get things like:

int f(int a) {
  return a + 1;
}

g++ -ffunction-sections -S -o - x.cc | grep .section

        .section        .text._Z1fi,"ax",@progbits

and really want to see that this is for f(int).  

It happens not to work though - I don't think the demangler can decode this when the leading ".text." is prepended to the section name.
