From 47a81c77fdd017227632c4df9a0b7b135b8a738d Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Tue, 15 May 2007 23:28:40 +0200 Subject: Restrict deep nesting of configfiles There is no point in restricting the number of included config- files, but there is a point in restricting the nestinglevel of configfiles: to avoid recursive inclusions. This is easily achieved by decrementing the static nesting-variable upon exit from cgit_read_config(). Also fix some whitespace breakage.
