[PATCH 0/3] un-break for-each-ref --ignore-case

This is a follow-up to this patch last September:

  https://public-inbox.org/git/79c946a2-532e-1c9b-7bf2-1f1ccbff721e@gmail.com/

The patch was the right thing to do, but:

 1. It needed a commit message.

 2. It needed a signoff.

 3. It needed a test, which then showed that there was _another_ bug. :)

This fixes 1 and 3, and the extra bug. I've added my signoff to Aleksandr's patch, as I think it is a trivial enough change to fall under the DCO part b. But Aleksandr, if you can give your explicit sign-off to include the patch in the project, that would be better still.

  [1/3]: t6300: add a test for --ignore-case
  [2/3]: for-each-ref: consistently pass WM_IGNORECASE flag
  [3/3]: ref-filter: avoid backend filtering with --ignore-case
