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. > static void copy_or_rename_branch(const char *oldname, const char *newname, int copy, int force) > { > struct strbuf oldref = STRBUF_INIT, newref = STRBUF_INIT, logmsg = STRBUF_INIT; > struct strbuf oldsection = STRBUF_INIT, newsection = STRBUF_INIT; > int recovery = 0; > + struct strbuf error_msg = STRBUF_INIT, empty = STRBUF_INIT; > + enum branch_validation_result res; > > if (!oldname) { > if (copy) > @@ -471,15 +502,13 @@ static void copy_or_rename_branch(const char *oldname, const char *newname, int > die(_("cannot rename the current branch while not on any.")); > } > > - if (strbuf_check_branch_ref(&oldref, oldname)) { > + if (strbuf_check_branch_ref(&oldref, oldname) && ref_exists(oldref.buf)) > + { 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)) {
