I tested it yet another time. When I give this command:

  $ ssh otherhost -t tmux new-session irb

and the variable EDITOR is not mentioned in "login.conf", it
will be empty. Ruby's ENV[ "EDITOR"] will be nil and TMux's
option "status-keys" will be "emacs".

Setting "EDITOR=vi" in login.conf/default/setenv solves the
problem. But nowhere else.
