[Orgmode] Possible Bug with :html-extension in HTML Exporter

[Ian Barton]

I am trying to export a project as php files. I realize that this an 
offence against the XHTML Gods, which is probably why I am having a problem.

The relevant bit of my org-publish-project-alist looks like:

 ("org-mobile"
          :base-directory "~/nfs/firewall/Documents/org/"
          :base-extension "org"
          :publishing-directory "~/nfs/firewall/public_html/org-mobile/"
          :recursive t
          :publishing-function org-publish-org-to-html
          :headline-levels 4             ; Just the default for this 
project.
          :auto-preamble t
          :auto-index t
          :html-extension php
          :index-filename "sitemap.org"
          :index-title "Sitemap"
      )

I have tried both php and "php". However, the exporter insists on the 
"One True Path" of exporting everything with a .html extension.

I am using df3fca503e9136edea8a1defe54926c3d3c03b63 
refs/remotes/origin/HEAD.
