Status on a feature branch

On a feature branch, every splice syncs with the upstream branch of the same name. Most upstreams don't have it, so the comparison is with their default branch, as for a PR. Where that has every commit already, the splice shows as unchanged, last. The others come first, and push would create their branch upstream: cli, which changed on feature, and parser and store, whose commits on main upstream doesn't have yet.

Output

setup.bash builds this state:

$ build_scenario scenario_many_splices

$ git checkout -q -b feature

$ echo "feature work" >> libs/cli/file.txt

$ git commit -q -am "feature work"

$ git splice status
On branch feature

  new, ahead 1                   libs/cli     push creates the branch
  new, ahead 1                   libs/parser  push creates the branch
  new, ahead 1, behind 1         libs/store   push creates the branch

  unchanged, no upstream branch  libs/http
  unchanged, no upstream branch  libs/theme

After the push, the upstream has the branch, and cli is up to date with it:

$ git splice push libs/cli
??   libs/cli: upstream has no 'feature' branch yet -- this push creates it
ok   libs/cli: pushed 4dd9993 to feature

$ git splice status
On branch feature

  new, ahead 1                   libs/parser  push creates the branch
  new, ahead 1, behind 1         libs/store   push creates the branch

  up to date                     libs/cli
  unchanged, no upstream branch  libs/http
