Is that because push_default variable needs to be looked at from
sha1_name.c when resolving "@{push}", optionally prefixed with the
name of the branch? I wonder if that codepath should know the gory
details of which ref at the remote the branch is pushed to and which
remote-tracking ref we use in the local repository to mirror that
remote ref in the first place?
What do we do for the @{upstream} side of the things---it calls
branch_get() and when the branch structure is returned, the details
have been computed for us so get_upstream_branch() only needs to use
the information already computed. The interesting parts of the
computation all happen inside remote.c, it seems.
So we probably would do something similar to @{push} side, which
would mean that push_default variable and the logic needs to be
visible to remote.c if we want to have the helper that is similar to
set_merge() that is used from branch_get() to support @{upstream}.
Hmmm, I have a feeling that "with default configuration, where does
'git push' send this branch to?" logic should be contained within
the source file whose name has "push" in it and exposed as a helper
function, instead of exposing just one of the lowest level knob
push_default to outside callers and have them figure things out.
Viewed from that angle, it might be the case that remote.c knows too
much about what happens during fetch and pull, but I dunno.
