ssh-agent module Implement a simple module that automatically launches the ssh-agent when you login and adds your default key. Useful for anyone that does remote work and thus doesn't have access to a keychain tool.

Force ssh-agent output to use bourne-style syntax On systems where the shell cannot be changed because of a strict security policy, ssh-agent will use the syntax of whatever the default $SHELL is. For instance, if the default shell is tcsh, ssh-agent will use the c-shell style (setenv). This change forces ssh-agent to use bourne-style syntax since that has to be later interpreted by zsh. Consequently, the environment file will contain `export' statements from now on (instead of `setenv').

add ssh-agent option to set default lifetime of identities By default, ssh-agent stores identities forever. It has an option to set a maximum lifetime for identites (useful to expire passphrase protected keys). Allow this option to be set using: zstyle :omz:plugins:ssh-agent lifetime <time>

ssh-agent: prevent environment file from flapping On an OS X laptop, the variable `$HOST` changes a lot depending on what wifi network you're connected to. This causes a lot of `~/.ssh/environment-$HOST` files to be created and causes multiple ssh-agents to created. Instead, use `scutil --get ComputerName` to get something more stable.

Use existing ssh-agent when invoking a sudo shell (#3891) When invoking a shell as root using ```sudo -s```, the ssh-agent plugin starts a new agent although it already exists. The problem boils down to a check if ssh-agent is running using ```ps x```. If that is extended to ```ps ax``` for root, then the existing ssh-agent will still work.
