Subject: [PATCH] Misleading error handling: utils_create_pid_file() should
 return 0 on success
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

fprintf returns a positive value on success, which is used as return
value for utils_create_pid_file(), which is odd. This is in preparation
for main() refactoring.
