From 147875fd25ca21c580102529dd51de15acae178c Mon Sep 17 00:00:00 2001 From: Stefan Beller Date: Mon, 12 Oct 2015 10:58:58 -0700 Subject: [PATCH] submodule-config: "goto" removal in parse_config() Many components in if/else if/... cascade jumped to a shared clean-up with "goto release_return", but we can restructure the function a bit and make them disappear, which reduces the line count as well. Also reformat overlong lines and poorly indented ones while at it. The order of rules to verify the value for "ignore" used to be to complain on multiple values first and then complain to boolean, but swap the order to match how the values for "path" and "url" are verified.
