[PATCH v2 0/4] branch -l deprecation revisited

This series replaces the contents of jk/branch-l-0-deprecation, jk/branch-l-1-removal, and jk/branch-l-2-reincarnation.

It implements the idea discussed in the subthread in:

  https://public-inbox.org/git/xmqqzi0hety4.fsf@gitster-ct.c.googlers.com/

Namely that "branch -l" would warn about deprecation only when we're not in list mode, and then we'll eventually jump straight to repurposing "-l" as "--list".

This gets us to the end result faster, without the annoying "-l doesn't mean anything" step in between, and without useless warnings on "git branch -l". It also sidesteps any pager issues since list mode will not print the warning.

The first 3 patches would become jk/branch-l-0-deprecate, and then the final one would become jk/branch-l-1-repurpose or similar. No third step required.

  [1/4]: t3200: unset core.logallrefupdates when testing reflog creation
  [2/4]: t: switch "branch -l" to "branch --create-reflog"
  [3/4]: branch: deprecate "-l" option
  [4/4]: branch: make "-l" a synonym for "--list"
