# Zsh before version 5.3.0 emulating POSIX sh(1) or Korn shell only sources the
# interactive shell startup file described in ENV if it's set after
# /etc/profile is sourced, but before ~/.profile is. The other shells I have
# tried (including modern shells emulating POSIX sh(1)) wait until after
# ~/.profile is read. This seems to have been fixed in Zsh commit ID fde365e,
# which was followed by release 5.3.0.
# Is this zsh masquerading as sh/ksh?
