This will be the option to include non-tracking remote branches. We could add
more fine-grained filtering flags, but I think --all is good enough and easier
to remember.
This patch also updates many of the test outputs to include synchronized remote
branches. I think verbose outputs will help catch future bugs.
As we can set HEAD to an arbitrary ref by using .reference_symbolic(), we don't
have to manage a ref that can also be valid as a branch name.
Fixes#1495
Apparently, it gets too verbose if the remote history is actively rewritten.
Let's summarize the output for now. The plan is to show the list of moved refs
instead of the full list of abandoned commits.
The problem is that the first non-working-copy commit moves the unborn current
branch to that commit, but jj doesn't "export" the moved branch. Therefore,
the next jj invocation notices the "external" ref change, which was actually
made by jj.
I'm not sure why we play nice by setting the "current" HEAD, but I *think* it's
okay to set the "new" HEAD and reset to the same commit to clear Git index.
This will probably help to understand why you've got conflicts after fetching.
Maybe we can also report changed local refs.
I think the stats should be redirected to stderr, but we have many other similar
messages printed to stdout. I'll probably fix them all at once later.
