+ * Changes by Clifford Wolf (god@clifford.at)
+ *
+ * [ 1998-06-13 ]
+ *
+ * *) A bugfix for the Page-Down problem
+ *
+ * *) Formerly when I used Page Down and Page Up, the cursor would be set
+ * to the first position in the menu box. Now lxdialog is a bit
+ * smarter and works more like other menu systems (just have a look at
+ * it).
+ *
+ * *) Formerly if I selected something my scrolling would be broken because
+ * lxdialog is re-invoked by the Menuconfig shell script, can't
+ * remember the last scrolling position, and just sets it so that the
+ * cursor is at the bottom of the box. Now it writes the temporary file
+ * lxdialog.scrltmp which contains this information. The file is
+ * deleted by lxdialog if the user leaves a submenu or enters a new
+ * one, but it would be nice if Menuconfig could make another "rm -f"
+ * just to be sure. Just try it out - you will recognise a difference!
+ *
+ * [ 1998-06-14 ]
+ *
+ * *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ * and menus change their size on the fly.
+ *
+ * *) If for some reason the last scrolling position is not saved by
+ * lxdialog, it sets the scrolling so that the selected item is in the
+ * middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.
