improving the ssh-agent man page

[Harald Dunkel]

Hi folks,

ssh-agent(1) appears to be unclear about it (IMHO), so I wonder if it would be possible to explicitly state in the man page that ssh-agent doesn't store any persistent data in the file system and that all the private keys and pass phrases are not known to the very next instance of ssh-agent?

For you this might be self-evident, but it is not.

Thanx in advance
Harri
