da95e25656 Merge branch 'gc/branch-recurse-submodules-fix'
A handful of obvious clean-ups around a topic that is already in
'master'.

* gc/branch-recurse-submodules-fix:
  branch.c: simplify advice-and-die sequence
  branch: rework comments for future developers
  branch: remove negative exit code
  branch --set-upstream-to: be consistent when advising
  branch: give submodule updating advice before exit
  branch: support more tracking modes when recursing

75388bf5b4 branch: support more tracking modes when recursing
"git branch --recurse-submodules" does not propagate "--track=inherit"
or "--no-track" to submodules, which causes submodule branches to use
the wrong tracking mode [1]. To fix this, pass the correct options to
the "submodule--helper create-branch" child process and test for it.

While we are refactoring the same code, replace "--track" with the
synonymous, but more consistent-looking "--track=direct" option
(introduced at the same time as "--track=inherit", d3115660b4 (branch:
add flags and config to inherit tracking, 2021-12-20)).

[1] This bug is partially a timing issue: "branch --recurse-submodules"
 was introduced around the same time as "--track=inherit", and even
 though I rebased "branch --recurse-submodules" on top of that, I had
 neglected to support the new tracking mode. Omitting "--no-track"
 was just a plain old mistake, though.

5cc9522b15 Merge branch 'gc/branch-recurse-submodules'
"git branch" learned the "--recurse-submodules" option.

* gc/branch-recurse-submodules:
  branch.c: use 'goto cleanup' in setup_tracking() to fix memory leaks
  branch: add --recurse-submodules option for branch creation
  builtin/branch: consolidate action-picking logic in cmd_branch()
  branch: add a dry_run parameter to create_branch()
  branch: make create_branch() always create a branch
  branch: move --set-upstream-to behavior to dwim_and_setup_tracking()

961b130d20 branch: add --recurse-submodules option for branch creation
To improve the submodules UX, we would like to teach Git to handle
branches in submodules. Start this process by teaching "git branch" the
--recurse-submodules option so that "git branch --recurse-submodules
topic" will create the `topic` branch in the superproject and its
submodules.

Although this commit does not introduce breaking changes, it does not
work well with existing --recurse-submodules commands because "git
branch --recurse-submodules" writes to the submodule ref store, but most
commands only consider the superproject gitlink and ignore the submodule
ref store. For example, "git checkout --recurse-submodules" will check
out the commits in the superproject gitlinks (and put the submodules in
detached HEAD) instead of checking out the submodule branches.

Because of this, this commit introduces a new configuration value,
`submodule.propagateBranches`. The plan is for Git commands to
prioritize submodule ref store information over superproject gitlinks if
this value is true. Because "git branch --recurse-submodules" writes to
submodule ref stores, for the sake of clarity, it will not function
unless this configuration value is set.

This commit also includes changes that support working with submodules
from a superproject commit because "branch --recurse-submodules" (and
future commands) need to read .gitmodules and gitlinks from the
superproject commit, but submodules are typically read from the
filesystem's .gitmodules and the index's gitlinks. These changes are:

* add a submodules_of_tree() helper that gives the relevant
  information of an in-tree submodule (e.g. path and oid) and
  initializes the repository
* add is_tree_submodule_active() by adding a treeish_name parameter to
  is_submodule_active()
* add the "submoduleNotUpdated" advice to advise users to update the
  submodules in their trees

Incidentally, fix an incorrect usage string that combined the 'list'
usage of git branch (-l) with the 'create' usage; this string has been
incorrect since its inception, a8dfd5eac4 (Make builtin-branch.c use
parse_options., 2007-10-07).
