I have investigated further.

hfy-face-at appears to be returning the right thing, but htmlfontify
seems not to produce overlapping fonts. So, looking at the first:


#define EMACS_BUFFER_H

from buffer.h with preproc-font installed.

This is from htmlfontify.el

#+begin_src html
  <span class="preprocessor">#</span>
  <span class="preprocessor">define</span>
  <span class="preprocessor-background"> </span>
  <span class="variable-name">EMACS_BUFFER_H</span>
#+end_src

And this is from htmlize.el

#+begin_src html
  <span class="preproc-font-lock-preprocessor-background">
    <span class="preprocessor">#define</span>
  </span>
  <span class="preproc-font-lock-preprocessor-background"> </span>
  <span class="preproc-font-lock-preprocessor-background">
    <span class="variable-name">EMACS_BUFFER_H</span>
  </span>
#+end_src

AFAICT, this all happens in hfy-fontify-buffer, and I haven't found the
energy to step through this yet.
