+     ===============================
+
+Requires libpdf which is a commercial library and therefore not
+part of SuSE LINUX.  As a replacement the `pdfcairo' terminal

+Author: Ethan A Merritt <merritt@u.washington.edu>
+Date:   Tue Mar 25 22:51:54 2025 -0700
+
+    hpgl: font name parsing overruns the string by one char
+    
+    if no comma is present in the font name.
+    E.g.
+       set term pcl
+       set title "Title" font "sans"    # no comma in font name
+       plot x

+
+Prevent buffer overflow when changing the default font to a maliciously
+crafted font name.
