From 372881ebfd5552ecb83450c7afea6a76f2df1a0b Mon Sep 17 00:00:00 2001 From: Jonathan Druart Date: Mon, 28 Dec 2015 15:47:01 +0000 Subject: [PATCH] Bug 15209: Check the parameter at the beginning of the subroutines It seems better to check if parameters exist at the beginning of a subroutine. It makes the code easier to read and there is 1 indentation level less.
