6.4.23 interesting feature

G'day all,

After updating to release 6.4.23, I noticed that the .pid file had an unusual size here, 9 bytes instead of 6.

$ cat ~/.fetchmail.pid
12345
42
$ 

The first line certainly corresponds to the running pid, and fetchmail -q continues to work fine. The second line represents the daemon interval, and the entry is created regardless whether I use -d on the command line or set daemon xx in the .rc file.

I did a very quick diff of the 6.4.22 and 6.4.23 sources and found no reference to pidfile, which makes me think this is not a change introduced by 6.4.23. Obviously, in my opinion, the daemon interval should not be recorded in the pid file.
