------------------------------------------------------------
revno: 102990
committer: Stefan Monnier <address@hidden>
branch nick: trunk
timestamp: Thu 2011-01-27 12:04:07 -0500
message:
  * lisp/htmlfontify.el: Make it obey the font-lock-face text property.
  Miscellaneous cleanup such as:
  - Don't hide expressions after a closing paren.
  - Move initial setq into let.
  - Hoist common parts out of ifs.
  (hfy-p-to-face, hfy-p-to-face-lennart): Remove.
  (hfy-face-at): Use get-text-property instead.
  (hfy-prop-invisible-p): Use invisible-p if available.
  (htmlfontify-manual): Use \\[...].
  (hfy-html-quote-regex): Use [...].
  (hfy-combined-face-spec): Simplify.
  (hfy-compile-face-map): Don't presume point-min==1.
  (hfy-css-name, hfy-buffer, htmlfontify-buffer): Use \' rather than $ to
  match end of string.
  (hfy-text-p): η-reduce.
  (hfy-tags-for-file): Receive cache-hash directly.
  (hfy-mark-tag-names): Adjust call.
