;;; Commentary:

;; This library sets some variables for git-email to make it work
;; better with mu4e.

;;; Code:

(require 'git-email)
(require 'mu4e-compose)

;;;###autoload
(define-minor-mode git-email-mu4e-mode
  "Mu4e integration for git-email.
If called interactively, toggle the mode.  A positive prefix ARG
enables the mode, any other prefix ARG disables it.  If called
from Lisp, enable the mode if ARG is omitted or nil."
  :group 'git-email
  :global t
  :init-value nil
  (if git-email-mu4e-mode
      (setq git-email-compose-email-function
            (lambda (to subject headers)
              (mu4e~compose-mail
               to
               subject
               ;; Remove "from" header, as it interferes with mu4e's
               ;; built in context feature.
               (seq-filter (lambda (header)
