[c-nsp] SSH public key authentication

[Tom Storey]

Playing with public key authentication on a 1811, and it seems that
when trying to paste in my public key, it wont accept more than 254
characters.

The public key is longer than 254 characters, however.

How does one go about entering more than 254 characters? Im sure Im
missing something really simple here, like a control character
sequence to allow more text to be entered on a following line
perhaps....?

Ive noticed that you can also use a hash instead of the full key text,
and this is working just fine. Are there any concerns using the hash
instead of full key text?

Thanks!
