Subject: [PATCH] .gdbinit: Have rp() work without a target [ci skip]

Useful for core dumps. It used to not work because:

    (gdb) p !""
    evaluation of this expression requires the target program to be active
    (gdb) p 0 == ""
    evaluation of this expression requires the target program to be active
