Comment # 5 on bug 843320 from Richard Biener

It already reasonably groups now:

(gdb) start

Temporary breakpoint 5, main (argc=1, argv=0x7fffffffde18)

libmpc3-debuginfo-1.0.2-4.55.x86_64 libmpfr4-debuginfo-3.1.2-11.53.x86_64

that is with gdb 8.0 (but also earlier versions I guess).  When librpm support
is enabled.
