Hi all,

I was finally able to solve this problem without tweaking anything inside
ox-html.el

I noticed that htmlize has provided few hooks and I used those.

Here is the code that I now have in my emacs init to disable fci (and
flyspell too) while htmlize-region is doing its job:

    (defvar modi/htmlize-initial-fci-state nil
      "Variable to store the state of `fci-mode' when `htmlize-buffer' is
called.")
    (defvar modi/htmlize-initial-flyspell-state nil
      "Variable to store the state of `flyspell-mode' when `htmlize-buffer'
is called.")

    (defun modi/htmlize-before-hook-fn ()
      (when (fboundp 'fci-mode)
        (setq modi/htmlize-initial-fci-state fci-mode)
        (when fci-mode
          (fci-mode -1)))
      (when (fboundp 'flyspell-mode)
        (setq modi/htmlize-initial-flyspell-state flyspell-mode)
        (when flyspell-mode
          (flyspell-mode -1))))
    (add-hook 'htmlize-before-hook #'modi/htmlize-before-hook-fn)

    (defun modi/htmlize-after-hook-fn ()
      (when (fboundp 'fci-mode)
        (when modi/htmlize-initial-fci-state
          (fci-mode 1)))
      (when (fboundp 'flyspell-mode)
        (when modi/htmlize-initial-flyspell-state
          (flyspell-mode 1))))
    (add-hook 'htmlize-after-hook #'modi/htmlize-after-hook-fn)

I would suggest that that fci-mode specific code be removed from the master.
