[c-nsp] display last lines of logging

[Justin Shore]

Agreed.  Tail would also be nice at times, especially -f when coupled 
with grep (-v).  Some of the less functionality has found its way into 
the CLI I noticed, at least as far as the searching goes.  Ie, sh run, 
then "/line con 0".  Does anyone else know?  I was surprised to see 
'include' and 'begin' support the beginning of line and end of line 
characters (^ & $) which I now use many times per day.  I don't know 
where all the CLI niceties are documented.

Basic 'for' and 'while' loops would be handy as well, especially if 
support for echoing termbells to the terminal could be added (echo -e 
"\a").  I'm sure we've also found ourselves repeating running a command, 
waiting for a certain subtle output change to indicate that something 
happened.

Whenever I deploy numerous devices at once I always find myself wishing 
for basic CLI variable support to ease my deployment woes.  I generally 
work around this with command line text editing tools on our Linux NOC 
box.  Still it would be handy to be able to define variables and use 
them within commands.
