I don't think supporting 
"b f()"

is needed...

And as a catch-all argument, gdb does not support "b f()"
either

Easily fixed by adding a re.escape() call, but this means
that 'b f()', if you've been doing that, will no longer work
to set a breakpoint.  The documentation doesn't claim that
'b f()' should work, but people may be used to typing this.

I've asked the 2.5 release manager about this issue.
