Comment # 2 on bug 1227767 from Neil Rickert

To me, this looks normal.

If you use the command:

 ssh-agent bash

Then it will export its environment variable to the "bash" shell that it
starts.

But if you just use:

 ssh-agent

then there is no subcommand to which it can export.

You should probably be using:

 eval `ssh-agent -s`

or

 eval $(ssh-agent -s)

When starting "ssh-agent" this way, its output is caught by the shell and then
run as a shell command.  And the shell then exports the needed variables.

Check the man pages for "ssh-agent".
