+Subject: [PATCH] Revert "settings.c: allow load_open_settings(NULL)."
+
+This reverts commit 1b2f39c24bb6591a4192377d9393f5c3e45cb5bd.
+
+The intention of that commit was to support the development of Uppity,
+by arranging that I could get a Conf populated with completely default
+values by calling load_open_settings(NULL,conf), with no risk of
+interference from the normal PuTTY saved sessions full of client-side
+configuration (which would have been confusing to apply unexpectedly
+in a server).
+
+So I arranged that a NULL session handle was never passed to the
+low-level read_setting_[type] functions, in case it caused a segfault.
+But I overlooked two things.
+
+Firstly, on Unix, read_setting_* is where we check the tree234 of data
+derived from X resources and/or -xrm command-line options. So if you
+don't call those functions at all (e.g. if you have no on-disk PuTTY
+saved configuration at all, not even Default Settings), you also don't
+get your X defaults honoured.
+
+Secondly, those functions themselves already all checked their
+argument for NULL before doing anything dangerous with it. So the
+thing I wanted to make possible was already possible _anyway_, without
+me having to do anything!
+
+So I'm exactly reverting that commit, because the _only_ thing it did
+was to introduce a bug in X resource handling.
