;; enrich gtags with dabbrev-code results (to emulate local variables).
;; To do this, add a list with both back-ends as an element in company-backends.
;;
-;; Known Issues:
-;; When point is at the very end of the buffer, the pseudo-tooltip appears very
-;; wrong, unless company is allowed to temporarily insert a fake newline.
-;; This behavior is enabled by `company-end-of-buffer-workaround'.
-;;
;;; Change Log:
;;
;; See NEWS.md in the repository.
