pass DISPLAY and SSH_ASKPASS through to ssh-agent if set

[kevinr]

This is a much smaller commit which I believe accomplishes the same goal as #31 and resolves #18.

In keeping with the goal of making ssh-ident behave as closely as possible to how the bare ssh binary behaves, I don't add any extra configuration options, I simply pass the environment variables through to ssh-agent if set.

Hi kevinr,

is this still the latest patch for DISPLAY and SSH_ASKPASS, or did you experience other issues after posting it here?
Would like to introduce them into the fork at https://github.com/ssh-ident/ssh-ident1
Any information would be great.

Regards
Maddes

Hey Maddes,

Yeah, this is the most recent patch. It worked until I stopped using ssh-ident at some point for unrelated reasons. :) It would be awesome to have it incorporated into the fork!

Best,

My actual idea when I saw that topic was: why not make the usage of -i optional.
Would passing the complete environment cause other issue?
