Does not work on Fish 2.5.0

[martinisoft]

Fish 2.5.0 fixed a bug with function definitions that now makes the init function with eval an invalid function. Here is the debug output:

function: Unexpected positional argument 'set'
- (line 1): begin;  function chefvm   set command "$1"   if test [ "$argv" -gt 0 ]     shift   end    switch "$command"     case shell       eval `chefvm "sh-$command" "$argv"`     case "*"       command chefvm "$command" "$argv";  end end
                    ^
