No {} around a single statement block of "if", especially when there
is no "else" that has multi-statement block that needs {}.

The case arms and their statements are indented by one level too much.
The lines are getting overlong. Find a good place to split, e.g.
strbuf_addf(error_msg, "%s",
!old_branch_exists ? connector_string : "");
Leave a single SP after each "," in an arguments list.
As Eric pointed out, this certainly smells like a sentence lego that
we would be better off without.

Opening brace { that begins a block comes at the end of the line
that closes the condition of "if"; if you found that your line is
overlong, perhaps do it like so instead:
if (strbuf_check_branch_ref(&oldref, oldname) &&
ref_exists(oldref.buf)) {
