[pgpool-hackers: 2400] Garbage output

[Tatsuo Ishii]

Usama,

Since your commit:
https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commit;h=a1ff51eea5a4e58e387ce3888a89bf056ea9f3c3

The regression test for 004.watchdog produces garbage output something
like this:

testing 004.watchdog...^@ok.

Actually "^@" is 0x00 (NULL). Probably because I use emacs shell, I
noticed it. You do not see it on an ordinary terminal. I guess
watchdog produces NULL in the log (stderr or stdout) somewhere.

Can you please fix it?

Best regards,
