This patch does not apply anymore.  Could you rebase it on the top of
master?

Well, when using “git format-patch” the option ’--base’ is helpful for
this kind of cases because it stores the base commit against which it
applies.  Then, anyone is able to easily rebase.

Maybe instead, I would move this as a local definition under
’melpa-recipe->origin’.

Why not ’identifier’?
