Rich,

Thank you, I will give that a shot.  FYI I discovered:

declare -x GPG_AGENT_INFO="/tmp/gpg-2uVMfE/S.gpg-agent:26095:1"

When I unset this env variable, ssh stopped trying to use pinentry to
acquire my passphrase.  However, I still do not understand how that
variable got set or how/why ssh behaves differently when it is set.
