MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 7db86dc (ctags: usability fix) removed function prototypes from tags file claiming "It makes no real sense to include function prototypes". But it is useful for quickly determining which header file developer needs to include to fix compilation. Now if someone wants to remove forward declarations (which I agree are baggage), write a postprocessing script.
