Commit Message
While reading info_checkpoints_command, I noticed variable printed:
...
const fork_info *printed = NULL;
...
for (const fork_info &fi : fork_list)
{
if (requested > 0 && fi.num != requested)
continue;
printed = &fi;
...
}
if (printed == NULL)
...
has pointer type, but is just used as bool.
Make this explicit by changing the variable type to bool.
Tested on x86_64-linux.

LGTM.
