Append an environment variable: 'env append'

[Palacios, Hector]

Hello,

You can append a string to an existing variable with:

	=> env set var ${var} anotherval

but I was wondering if it would be interesting to have an explicit 
'append' subcommand that facilitates this:

	=> env append var anotherval

I would find it useful for variables that contain lists, like kernel 
arguments, and such.
Has this been discussed in the past?

Thanks
