To clarify, you are concerned that, as in your image, "xxxximport" is
highlighted a different colour from "sys", but this is not reflected in
htmlfontify-buffer?

In my hands that line is coming in a single colour. Looking at
buffer-substring, I get....

#("+xxxxxxxxxxxximport sys" 0 1 (fontified t face diff-indicator-added) 1 23 
(fontified t face diff-added))


i.e. there is only a single font, after the "+". The equivalent HTML
looks like this....

</span><span class="diff-indicator-added">+</span><span 
class="diff-added">xxxxxxxxxxxximport sys
</span>

which seems correct to me. I've tried 24.4 and current emacs-25 branch.

Am I looking at the right thing?
