Description of problem:
pidof failed to get the pid with full path. This could be a same problem in bug#567295.

Version-Release number of selected component (if applicable):
SysVinit-2.86-14

How reproducible:
Not easy.  

Steps to Reproduce:
1.write a small program use readlink(path,pathname,maxbuf) and print out pathname for all processes. See killall5.c readproc() method for example.
2.If lucky enough, one could see some junk character after the pathname print out. Example /path1/path2/path3/program@@@.
3.With the pathname from step 2, run pidof with it. Example /sbin/pidof /path1/path2/path3/program.  One shouldn't see any PID return.
  
Actual results:
can not find the PID

Expected results:
should find the PID

Additional info:
readlink doesn't seems to add end of string to pathname.
The problem is in killall5.c function readproc(), 
		if (readlink(path, p->pathname, PATH_MAX) == -1) {
		if(pathnameLength==-1){
			p->pathname = NULL;
		} else {
			p->pathname[PATH_MAX-1] = '\0';
		}
believe it should change to
		int pathnameLength=readlink(path, p->pathname, PATH_MAX);
		if(pathnameLength==-1){
			p->pathname = NULL;
		} else {
			p->pathname[pathnameLength] = '\0';
		}
