[PATCH v2 2/2] remote: resolve "simple" @{push} when pushing to another remote

In-Reply-To: <pull.2466.v2.git.git.1793433841.gitgitgadget@gmail.com>

From: Harald Nordgren <haraldnordgren@gmail.com>

With push.default left at "simple", a branch whose upstream is on one remote and whose push remote is another gets pushed by "git push" to a branch of the same name on the push remote. But @{push} for that branch fails with "cannot resolve 'simple' push to a single destination". As a result "git status" shows the "git push" hint under the comparison with the upstream, even though "git push" goes elsewhere, and leaves out the comparison with the push branch when status.compareBranches asks for it.

"git push" learned to handle "simple" this way in ed2b18292b (push: change `simple` to accommodate triangular workflows, 2013-06-19). When @{push} was added in e291c75a95 (remote.c: add branch_get_push, 2015-05-21), its "simple" case only covered pushing back to the remote the branch is fetched from, where the upstream must have the same name.

Make @{push} follow "git push". When the push remote is not the remote of the branch, resolve to the branch of the same name on the push remote, as "current" does.

The test added in 9bf9eed093 (remote: fix leak in branch_get_push_1() with invalid "simple" config, 2026-01-19) relied on a different push remote being invalid for "simple". Use an upstream with a different name on the same remote instead, so that it still exercises the error path.
