[PATCH 13/15] prlimit: enhance examples section of the man page

Add various examples to the man page, e.g. demonstrating setting
limits using short options, showing that the --pid option can be
used in random positions, how to use the "-1" notation for the
"unlimited" value, and that prlimit takes the values from the arguments
last set.

  .SH EXAMPLES
  .IP "\fBprlimit \-\-pid 13134\fP"
  Display limit values for all current resources.
-.IP "\fBprlimit \-\-pid 13134 \--rss --nofile=1024:4095\fP"
+.IP "\fBprlimit \--rss \-\-pid 13134 --nofile=1024:4095\fP"
  Display the limits of the RSS and set the soft and hard limits for the 
amount
  of open files to 1024 and 4095, respectively.
-.IP "\fBprlimit \-\-pid 13134 --nproc=512:\fP"
+.IP "\fBprlimit \-\-pid 13134 -n512:\fP"
  Modify only the soft limit for the amount of processes.
-.IP "\fBprlimit \-\-pid $$ --nproc=unlimited\fP"
+.IP "\fBprlimit \-\-pid=$$ --nproc=unlimited\fP"
  Set the amount of processes for both soft and ceiling values to unlimited.
+.IP "\fBprlimit \-p$$ -n-1:\fP"
+Likewise, but only for the soft limit and using the "-1" notation.
+.IP "\fBprlimit \-p$$ -n:1000 -n\fP"
+Set the hard NPROC limit to 1000 and display its value.
+.IP "\fBprlimit \-p$$ -n100:200 -n300 -n400: -n:500\fP"
+Example to demonstrate that prlimit uses the values of the options last 
set.
+Here it will set the soft NPROC limit to 400 and the hard limit to 500.
