+#   version 34: fix colorization of nicks containing regex-special characters
+#               (e.g., hyphens) — re.escape() was applied before dictionary lookup,
+#               causing escaped nick form (e.g., 'flash\-code') to not match unescaped
+#               dict keys (e.g., 'flash-code'). Keep nick unescaped for lookup/display,
+#               escape only when building the line-matching regex.

 #   version 33: add many improvements, features, and fixes
