Kurtis Rader 905766fca2 Hoist for loop control var to enclosing scope (#4376) ...

* Hoist `for` loop control var to enclosing scope

It should be possible to reference the last value assigned to a `for`
loop control var when the loop terminates. This makes it easier to detect
if we broke out of the loop among other things.  This change makes fish
`for` loops behave like most other shells.

Fixes #1935

* Remove redundant line
