The '--set-upstream' option of branch was deprecated in,
b347d06bf branch: deprecate --set-upstream and show help if we
detect possible mistaken use (Thu, 30 Aug 2012 19:23:13 +0200)
It was deprecated for the reasons specified in the commit message of the
referenced commit.
Make 'branch' die with an appropraite error message when the '--set-upstream'
option is used.
Note that there's a reason behind "dying with an error message" instead of
"not accepting the option". 'git branch' would *accept* '--set-upstream'
even after it's removal as a consequence of,
Unique prefix can be abbrievated in option names
AND
'--set-upstream' is a unique prefix of '--set-upstream-to'
(when the '--set-upstream' option has been removed)
In order to smooth the transition for users and to avoid them being affected
by the "prefix issue" it was decided to make branch die when seeing the
'--set-upstream' flag for a few years and let the users know that it would be
removed some time in the future.
The before/after behaviour for a simple case follows,
$ git remote
origin
Before,
$ git branch
* master
$ git branch --set-upstream origin/master
The --set-upstream flag is deprecated and will be removed. Consider using --track or --set-upstream-to
Branch origin/master set up to track local branch master.
$ echo $?
0
$ git branch
* master
origin/master
After,
$ git branch
* master
$ git branch --set-upstream origin/master
fatal: the '--set-upstream' flag is no longer supported and will be removed. Consider using '--track' or '--set-upstream-to'
$ echo $?
128
$ git branch
* master

Changes in v3:
A few tweaks to the following:
* Commit message
* Error message (the one shown when '--set-upstream' is seen)
* Updated the corresponding message in the options structure
* Documentation
A query,
I see the following code in the code path a little above the die statement
added in this change,
if (!strcmp(argv[0], "HEAD"))
die(_("it does not make sense to create 'HEAD' manually"));
It does seem to be doing quite a nice job of avoiding an ambiguity that could
have bad consequences but it's still possible to create a branch named 'HEAD'
using the '-b' option of 'checkout'. Should 'git checkout -b HEAD' actually
fail(it does not currently) for the same reason 'git branch HEAD' fails?
My guess is that people would use 'git checkout -b <new_branch_name> <starting_point>'
more than it's 'git branch' counterpart.
