I really don't want the filter scripts to perform any more work than
necessary, so maybe we could to something like this instead:

diff --git a/filters/syntax-highlighting.sh b/filters/syntax-highlighting.sh
index 6283ce9..183bd68 100755
--- a/filters/syntax-highlighting.sh
+++ b/filters/syntax-highlighting.sh
@@ -42,4 +42,8 @@ EXTENSION="${BASENAME##*.}"
 # map Makefile and Makefile.* to .mk
 [ "${BASENAME%%.*}" == "Makefile" ] && EXTENSION=mk
 
+# This is for highlight v2
 exec highlight --force -f -I -X -S $EXTENSION 2>/dev/null
+
+# If you're using highlight v3, use this command instead:
+#exec highlight --force -f -I -O xhtml -S $EXTENSION 2>/dev/null
