Since commit e87ebca2a7, setting org-special-ctrl-k to t no longer protects tags if when pressing C-k (org-kill-line) in the middle of a headline. The expected behavior is described in the docstring for org-special-ctrl-k: "When in the middle of the headline text, kill the headline up to the tags."
Take the following example: * Headline :tag: If I hit C-k with the cursor on the letter "l" on the example above, I expect to get this... * Head :tag: Instead, I get this... * Head I think this is because when (looking-at org-tag-line-re) is called on line 22840, the cursor is in the middle of the line, whereas org-tag-line-re expects it to be at the beginning of the line.
