Description of problem:

Tried to add sshkey file with empty content, got the following result:
[root@dhcp-8-252 home]# rhc sshkey add dddd ~/.ssh/empty.pub
File '/root/.ssh/empty.pub' does not appear to be a recognizable key file (public key at  is not
valid). You may specify the '--confirm' flag to add the key anyway.

**There should be a key path after the "(public key at".

Tried to add sshkey file with "ssh-rsa aasd" content:
[root@dhcp-8-252 home]# rhc sshkey add dddd ~/.ssh/empty.pub
File '/root/.ssh/empty.pub' does not appear to be a recognizable key file (not a public key ""). You
may specify the '--confirm' flag to add the key anyway.

**There should be key content in the "".
