You let extra whitespace changes creep in.

This seems like doing this either the paranoid or hard way.
Why not:
const char *stats_type = NULL;
...
case 'x':
stats_type = optarg;
break;
...
if (stats_type)
snprintf(hist_name, sizeof(hist_name),
"%s/.%s_ifstat.u%d", P_tmpdir, stats_type,
getuid());
else
snprintf(hist_name, sizeof(hist_name),
"%s/.ifstat.u%d", P_tmpdir, getuid());
Since:
1) optarg points to area in argv that is persistent (avoid copy)
2) don't need is_extended flag value then
Please cleanup and resubmit.
