[c-nsp] additional info before "show" commands output

[Andriy A. Yerofyeyev]

I just got access to cisco switch which was configured strange enough.
It show me two additional show commands (part of) before output of each
show command.
Here is an example:

You can easily figure out what I am talking about.(first two lines)

Just wondering , how it can be ? and how I can configure such behavior ?

I thought , may be it some game with aliases, but it still not clear for
me..

alias interface x do
