Nope, not there either.

FreeBSD ditched the traditional Berkeley csh a while back and
replaced it with tcsh, with a link to /bin/csh, so that when you
run `csh` on FreeBSD you're really running `tcsh`.  Tcsh
supports arrow key navigation for command recall, as you noted,
but actual csh never has; it only supported the `!` style
history mechanism.
