Indeed, and this commit pops `org-table-last-alignment' if the first
column has been removed by `org-table-clean-before-export'. The same
problem must have caused a one-off error when setting the alignment in
LaTeX tables, bu it seems nobody has noticed this so far. Anyway,
also this is fixed now.
A `save-excursion' around a call to org-table-align make point end up
*before* the table. The reason is that a table align replaces the
entire table, including the newline before it. When the table is
removed in order to be replaced, the marker created by
`save-excursion' slips. `org-table-align' has it's own, built-in
`save-excursion' by remembering the line and column where the cursor
was before the align.

This commit fixes the issue.
`org-export-latex-first-lines' was rather stupid and would
discard the end of the region with the region was active.
Thanks to Holst Thomas for this bug report.
Many different people want to set many different variables in a
buffer-local way for export. This cannot be done with file variables,
because the Org buffer is not current while the exporter is running.
Lots of variables can be set with the #+OPTIONS lines, but finding
abbreviations goes only so far.
Therefore we have now a general mechanism that can be used to bind
variables during export operations.
a line like: #+BIND: variable value
will bind the variable to value. For example,
the line
>> #+OPTIONS: toc:nil
can now equivalently be written as
>> #+BIND: org-export-with-toc nil
Some propel process LaTeX filed not directly to pdf, but go
through dvi and then to ps or pdf. In that case, allowed images
are ps and eps files, not pdf and jpg.
This commit adds the two extensions, so that export using that
alternative path can be supported better. However, it is up to the
user to make sure that the images are actually compatible with the
backend.
All export commands now push the result to the kill ring by default.
This is subject to the variable `org-export-push-to-kill-ring'.
Also, this commit adds a new variable
`org-export-show-temporary-export-buffer' which can be used to turn
off the display of the temporary buffer containing the exported text.
Since this stuff is now automatically pushed onto the kill ring, some
people might prefer not to see this buffer.

It is actually the correct way to do this, and I have
implemented this change.

This is hopefully fixed now.
Chris Gray had the idea to have arbitrary blocks turned in LaTeX
environments and HTML divs. These three new hooks allow
implementation has an add-on rather than a patch.

These problems were caused by a regular expression for
matching latex macros with arguments, that did not allow any
newlines. Now we have a much better regexp, that even
allows for three levels of nested braces.
Time stamps in LaTeX export now also honor custom time stamp formats.
Furthermore, the new option `org-export-latex-timestamp-markup' can
specify special markup for time stamps.
