I've been thinking of starting a cli/cli-utils.c file and putting shared
CLI parsing code there.  This seems like a good candidate, WDYT?
I can do the moving.

Pedro>    if (p == NULL)
Pedro> -    /* Empty line means refer to the last breakpoint.  */
Pedro> -    return breakpoint_count;
Pedro> +    return 0;

I was surprised that this didn't imply any other changes, but I looked
at a bunch of calls into this code and I couldn't see anything.
