[PATCH] Test for correct usage of columnWidth in clang fixit hints.

[Jordan Rose]

  Let's drop the CHECK-MACHINE case, but otherwise this looks good.

  However, if you care about keeping the test files in sync, how about just making this file only contain CHECK lines, and actually compile the original fixit-unicode.c? That allows you to specify the XFAIL properly while avoiding duplication.
