Nicolas Goaziou 212828c556 org-list: correctly handle counters in `org-list-parse-list' 
* lisp/org-list.el (org-at-item-counter-p): new function.
(org-list-parse-list): handle counters and list depth.
(org-list-to-generic): a special string is used when an item has a
counter.
(org-list-to-latex): use new special string for counters. This fixes
the counter bug in LaTeX export, as the enumi counter was the only one
modified.
* lisp/org-latex.el (org-export-latex-lists): use new
`org-list-parse-list' output.

"Alist of LaTeX classes and associated header and structure.
If #+LaTeX_CLASS is set in the buffer, use its value and the
associated information. Here is the structure of each cell:
\(class-name
header-string
(numbered-section . unnumbered-section\)
...\)
The header string
-----------------
The HEADER-STRING is the header that will be inserted into the LaTeX file.
It should contain the \\documentclass macro, and anything else that is needed
for this setup. To this header, the following commands will be added:
- Calls to \\usepackage for all packages mentioned in the variables
`org-export-latex-default-packages-alist' and
`org-export-latex-packages-alist'. Thus, your header definitions should
avoid to also request these packages.
- Lines specified via \"#+LaTeX_HEADER:\"
If you need more control about the sequence in which the header is built
up, or if you want to exclude one of these building blocks for a particular
class, you can use the following macro-like placeholders.
[DEFAULT-PACKAGES] \\usepackage statements for default packages
[NO-DEFAULT-PACKAGES] do not include any of the default packages
[PACKAGES] \\usepackage statements for packages
[NO-PACKAGES] do not include the packages
[EXTRA] the stuff from #+LaTeX_HEADER
[NO-EXTRA] do not include #+LaTeX_HEADER stuff
[BEAMER-HEADER-EXTRA] the beamer extra headers
So a header like
\\documentclass{article}
[NO-DEFAULT-PACKAGES]
[EXTRA]
\\providecommand{\\alert}[1]{\\textbf{#1}}
[PACKAGES]
will omit the default packages, and will include the #+LaTeX_HEADER lines,
then have a call to \\providecommand, and then place \\usepackage commands
based on the content of `org-export-latex-packages-alist'.
If your header or `org-export-latex-default-packages-alist' inserts
\"\\usepackage[AUTO]{inputenc}\", AUTO will automatically be replaced with
a coding system derived from `buffer-file-coding-system'. See also the
variable `org-export-latex-inputenc-alist' for a way to influence this
mechanism.
The sectioning structure
------------------------
The sectioning structure of the class is given by the elements following
the header string. For each sectioning level, a number of strings is
specified. A %s formatter is mandatory in each section string and will
be replaced by the title of the section.
Instead of a cons cell (numbered . unnumbered), you can also provide a list
of 2 or 4 elements,
(numbered-open numbered-close)
or
(numbered-open numbered-close unnumbered-open unnumbered-close)
providing opening and closing strings for a LaTeX environment that should
represent the document section. The opening clause should have a %s
to represent the section title.
Instead of a list of sectioning commands, you can also specify a
function name. That function will be called with two parameters,
the (reduced) level of the headline, and the headline text. The function
must return a cons cell with the (possibly modified) headline text, and the
sectioning list in the cdr."

`pdflatex', maybe mixed with a call to `bibtex'. Org does not have a clever
mechanism to detect which of these commands have to be run to get to a stable
result, and it also does not do any error checking.
By default, Org uses 3 runs of `pdflatex' to do the processing. If you
have texi2dvi on your system and if that does not cause the infamous
egrep/locale bug:
http://lists.gnu.org/archive/html/bug-texinfo/2010-03/msg00031.html
then `texi2dvi' is the superior choice. Org does offer it as one
of the customize options.

If there is an active region, export only the region. The prefix
ARG specifies how many levels of the outline should become
headlines. The default is 3. Lower levels will be exported
depending on `org-export-latex-low-levels'. The default is to
convert them as description lists.
HIDDEN is obsolete and does nothing.
EXT-PLIST is a property list with
external parameters overriding org-mode's default settings, but
still inferior to file-local settings. When TO-BUFFER is
non-nil, create a buffer with that name and export to that
buffer. If TO-BUFFER is the symbol `string', don't leave any
buffer behind but just return the resulting LaTeX as a string.
When BODY-ONLY is set, don't produce the file header and footer,
simply return the content of \\begin{document}...\\end{document},
without even the \\begin{document} and \\end{document} commands.
