Add a "button" option for magit-revision-insert-related-refs

[vincentbernat]

Hey!

Inserting related refs is painly slow on some repositories. For example, for Linux repository, it can takes several seconds. This can be fixed by setting magit-revision-insert-related-refs to nil. However, the information can be quite useful. It could be toggled on demand by allowing to set 'button for magit-revision-insert-related-refs. Upon clicking on the button, the related refs would be computed and the button would be replaced by the result.

[ I realize that 1) you're asking for Magit to support this and 2) you're asking for a button, but in case it's useful to you or others... ]

I've set magit-revision-insert-related-refs to nil in my configuration for a long time. When I want to see the refs, I use this custom command:

(defun km/magit-revision-insert-related-refs ()
  (interactive)
  (let ((magit-revision-insert-related-refs t))
    (magit-refresh)))

(define-key magit-revision-mode-map (kbd "C-c C-r")
  #'km/magit-revision-insert-related-refs)

Thanks, that's pretty useful!
