Handle case matches on special characters (extra boost).

This is a fix for #3263.

@JeffryBooher I saw that @marcelgerber marked #3263 as a dupe of #3971 but it turns out that the change that landed on master didn't fix #3263. I took a quick look and realized that the fix for #3971 did not spot case matches on the special characters, which I think is actually pretty important.

If you look at the goodRelativeOrdering tests, you'll see that there were some tweaks to the expected ordering of things. It's impossible to make everyone happy all of the time. But, with this change you'll pretty reliably see things bubble to the top if you match case on the specials.

@dangoor thanks. I will take a look in a bit. Thanks for doing this.

LGTM. All tests pass, Quick View promotes Case matches to the top of the list. Nice!
