Interpolation Bypasses Minimum Prefix Length

[garrett-hopper]

Is there a reason interpolation bypasses the minimum prefix length?

It seems to be behaving strangely with the new 0.12 syntax. Perhaps in the past it made sense to start completing as soon as "${ was typed, however now with 0.12 it's strange to show completions as soon as [ is typed for variable assignment. (variable = [ starts showing all completions)

I propose changing it to:

         (`(interpolation . ,_)
          ;; (cons (car (last (split-string (nth 1 context) "\\."))) t)
          (car (last (split-string (nth 1 context) "\\.")))
          )
