Bug#420454: openssh-client: Please include a LD_PRELOAD enabled ssh-agent wrapper

[Josselin Mouette <joss@debian.org>]

Package: openssh-client
Version: 1:4.3p2-10
Severity: wishlist
Tags: patch

Because it is a setgid binary, ssh-agent does not propagate some 
environment variables like LD_PRELOAD. This is a known problem according 
to the documentation, which suggests to write a wrapper.

It would be better to include such a wrapper in the package itself, so 
I'm attaching one.
