    Use `unwind-protect' for :after-exit
    
    * hydra.el (hydra--make-defun): Update.
    
    This change makes "C-g" work for this hydra:
    
    (defhydra hydra-goto-line (global-map "M-g"
                               :pre (linum-mode 1)
                               :after-exit (linum-mode -1)
                               :exit t)
      ("g" goto-line "line")
      ("c" goto-char "char"))
