+#  The existing calculation of Y_INC make no allowance for the size of the
+#  inner frame of the input field.  When the input field text height + the
+#  inner frame size exceed the height of the prompt text this results in
+#  misalignment and artefacts being left behind when erasing characters 
+#  with tails (such as 'j').
+#
+#  The following resource settings can be used to reproduce the issue:
+#    xlogin*face:            Helvetica-30
+#    xlogin*promptFace:      Helvetica-16:bold
+#    xlogin*innerFramesWidth: 8
+
+#  This patch resolves both issues.
