That would be great.

Not completely right.  It is precisely remote.<branch>.fetch I'm
needing, to be able to locate which remote a parent branch belongs to
when creating a stack.  It may be that the problem is git-remote being
too limited, and if we implement the functionnality at that level,
then maybe we can ignore those config settings.  But maybe not, since
I'd like stack creation to record a remote.<stack>.fetch entry.

IMHO, that'd be the easiest way to shoot ourselves in the foot :)

OTOH, it is equally easy (if not easier) to call "git repo-config
--get" or --get-all when needed :)
