[PATCH v2 0/4] branch --recurse-submodules: Bug fixes and clean ups

["Glen Choo via GitGitGadget" <gitgitgadget@gmail.com>]

Thanks for the feedback, all. This version incorporates most of the
suggestions (which were pretty small anyway).

== Patch organization

Patches 1-2 are bugfixes, 3-4 are clean ups.

Patch 1 fixes a bug where "git branch --recurse-submodules" would not
propagate the "--track" option if its value was "--no-track" or
"--track=inherit".

Patch 2 fixes a bug where "git branch --recurse-submodules" would give
advice before telling the user what the problem is (instead of the other way
around).

Patch 3 fixes some old inconsistencies when "git branch --set-upstream-to"
gives advice and when it doesn't.

Patch 4 replaces exit(-1) with exit(1).

== Changes

Since v1:

 * Patch 1: reword the --track comments to be prescriptive
 * Patch 3: remove a now-unnecessary die(). I didn't include a suggestion to
   inline the advice string to save reviewers the trouble of proofreading
   (and the format string has no placeholders anyway, so I don't think we'd
   get much benefit out of typechecking). We can inline it in another
   series.

Glen Choo (4):
  branch: support more tracking modes when recursing
  branch: give submodule updating advice before exit
  branch --set-upstream-to: be consistent when advising
  branch: remove negative exit code
