Hi,
Quick nitpicks.

Whitespace is odd here. Maybe this case could be factored out as a
new function to make room on the right margin and make cmd_branch()
easier to read straight through.

Message should go on stderr and be guarded with an advice option (see
advice.c).
Like this:
const char *arg;
...
if (argc != 1 || !advice_old_fashioned_set_upstream)
return 0; /* ok. */
arg = argv[0];
advise("If you wanted to make '%s' track '%s', do this:",
head, arg);
if (branch_existed)
advise(" $ git branch --set-upstream-to='%s' '%s'",
old_upstream, arg);
else
advise(" $ git branch -d '%s'", arg);
advise(" $ git branch --set-upstream-to='%s'", arg);
If an argument contains single-quotes, the quoting will be wrong, but
that's probably not worth worrying about.
Hope that helps,
Jonathan
