Hi

/proc/*/cmdline contains one extra <nul> which makes pgrep,pkill and ps misbehave

on cygwin
$ cat /proc/self/cmdline |od -c
0000000   c   a   t  \0   /   p   r   o   c   /   s   e   l   f   /   c
0000020   m   d   l   i   n   e  \0  \0
0000030
note the terminating <nul><nul>

on linux(trustix)
baf AT xxx ~/procps$  cat /proc/self/cmdline |od -c
0000000   c   a   t  \0   /   p   r   o   c   /   s   e   l   f   /   c
0000020   m   d   l   i   n   e  \0
0000027

This diff makes
sleep 100&
pgrep -fx "sleep 100"
#fail
#but
pgrep -fx "sleep 100 "
#works
