Re: [PATCH v5 1/6] pull: rename pull.rename to pull.mode

["Philip Oakley" <philipoakley@xxxxxxx>]

From: "Felipe Contreras" <felipe.contreras@xxxxxxxxx>
> Also 'branch.<name>.rebase' to 'branch.<name>.pullmode'.

Sorry I haven't commented earlier. Because the 0/6 explanation isn't a
commit, a few extra words would be useful to capture what the 0/6 cover
letter said to start the patch series cleanly/clearly e.g. start with

   Begin the "Reject non-ff pulls by default" process by creating new
   config variables which will allow extra options, to replace the old 
pull
   configuration options.

I didn't immediately grasp why the 'replacement' was happening, rather
than it being a creation and a deprecation.

I'd think it useful to add that:
   branch.<name>.rebase is deprecated.
given the large amount of internet cruft about this older config
variable name

Add?:
