From 4b0d1eebe95b8ed187ff06ae46d69d517c2b759f Mon Sep 17 00:00:00 2001 From: Jeff King Date: Fri, 11 Mar 2016 17:36:45 -0500 Subject: [PATCH] setup: document check_repository_format() This function's interface is rather enigmatic, so let's document it further. While we're here, let's also drop the return value. It will always either be "0" or the function will die (consequently, neither of its two callers bothered to check the return).
