Subject: ksh: make $(< filename) error output include the errno string.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=4fae8b7728edbfad797de65aa6679272c6937d35;p=openbsd

ksh: make $(< filename) error output include the errno string.
This is more consistent with how bash, zsh and ksh93 behave and
makes $(< filename) more of a drop-in replacment for $(cat filename).
