* contrib/lisp/org-export.el (org-export-snippet-backend): New
function.
(org-export--skip-p): Remove automatic skip of export snippets.
* EXPERIMENTAL/org-e-ascii.el (org-e-ascii-export-snippet): Use new
function.
* EXPERIMENTAL/org-e-html.el (org-e-html-export-snippet): Use new
function.
* EXPERIMENTAL/org-e-latex.el (org-e-latex-export-snippet): Use new
function.
* EXPERIMENTAL/org-e-odt.el (org-e-odt-export-snippet): Use new
function.
* testing/contrib/lisp/test-org-export.el: Add test.
The idea behind this change is that a given back-end may decide to
keep an export snippet not directly targetted at it (i.e. a beamer
back-end that would want to keep latex snippets). Hence, filtering
snippets is on back-ends side, and a new function is added to help
them in that task.
* contrib/lisp/org-export.el (org-export-get-parent): New function.
(org-export-data, org-export-get-previous-element,
org-export-get-next-element): Use new function.
* EXPERIMENTAL/org-e-ascii.el (org-e-ascii-item): Use new function.
Refactor code.
(org-e-ascii-paragraph): Use new function.
* EXPERIMENTAL/org-e-latex.el (org-e-latex-item): Use new function.
* EXPERIMENTAL/org-e-html.el (org-e-html-item): Use new function.
* EXPERIMENTAL/org-e-odt.el (org-e-odt-item): Use new function.
* contrib/lisp/org-export.el (org-export-dispatch)
(org-export-dispatch-ui): Add new entries for the new HTML
exporter.
* EXPERIMENTAL/org-e-html.el: New file. This is a very rough
cut based out on org-xhtml.el and org-e-latex.el. The file
retains all the LaTeXisms in either commented form or
otherwise. This is deliberate so as to have a quick look at
the reference implementation. Retaining the organization
style of org-xhtml.el would enable easy creation of
org-e-odt.el by simply replacing e-html with e-odt for the
most part.
The changes here covers fairly a good ground - say 90% - of my
unit test file.
