From 831651fde8f8a8d90543917a8783962aa1a534bf Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Mon, 6 Jan 2014 14:45:21 +0100 Subject: safe_create_leading_directories(): add explicit "slash" pointer Keep track of the position of the slash character independently of "pos", thereby making the purpose of each variable clearer and working towards other upcoming changes.
