This is a bug report with a patch. Please review the patch and
merge it to the emacs official source tree if appreciated.
To reproduce a bug:
1. Make a new verilog-mode buffer and put following small code to the buffer:
--------------------------------<cut begin>-
// -*- verilog -*-
function x;
endfunction
--------------------------------<cut end>---
2. M-x toggle-debug-on-error
3. M-x htmlfontify-buffer
You will get following backtrace.
--------------------------------<cut begin>-

It seems that htmlfontify.el doesn't consider face alias which
is used to mark obsolete face like `font-lock-reference-face'.
