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. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
