The problem is in your .cshrc .  When vi forks a tcsh to expand the
variable, the tcsh runs your .cshrc, which runs bindkey, which sends a
control string to stdout.  To fix this, you need to conditionalize your
.cshrc:

if ($?prompt) then
    /usr/sbin/bindkey -l f1,push
    /usr/sbin/bindkey -l f2,pop
endif

This way, bindkey is only run if you start up a tcsh (or csh) for normal,
interactive use.  Note that if you set your prompt in your .cshrc it should
be done after the `if' (and preferably inside it!).  Most of my .cshrc sits
inside the `if' statement: all but my PATH definition and commands to protect
me from myself (such as "alias rm \rm -i").
