[PATCH] ps/libproc.a is missing clone/fork process information

A number of people using cloned process (mostly via the LinuxThread package)
have complained that the current ps command is unable to hide cloned processes
and to only show forked one. The (very ;-) simple 2.1.121 patch attached here
would allow the procps commands & library to differenciate processes between
"cloned" and "forked" ones, by reporting their current "p->exit_signal"
(SIGCHLD for a forked one, other for a cloned one) as a value of the
/proc/<pid>/stat output.

Best regards,
