Date Range in view was ignoring separator setting

I saw that the first time that I switched the formatter. I was still able to save it with either option. When I clicked on the field setting again, it was no longer set in red and showed the correct separator.

What version of Drupal are you on?

I have cracked the code and found the source of the issue.

This will need a back port for the 1.x branch.
