[O] [PATCH] org-latex: Don't append newline to end of footnote

[Lawrence Mitchell]

* lisp/org-latex.el (org-export-latex-preprocess): Don't add a newline
character to a processed footnote.

The extra newline before the closing } character in a footnote
confuses the list parsing code.  The } appears at the beginning of a
line, so it looks like the end of the list.  LaTeX gobbles the space
anyway, so don't add it.

The list is closed incorrectly.  This appears to be a problem in
the interaction between the list parsing and footnote processing
code.  When exporting footnotes, we add a newline at the end, so
in the above example the intermediate file seen by the list
processing code is:

| * Project Participants
| - Rainer M Krug :: \footnote{My email
| }
| ORG-LIST-END-MARKER
| My address

The } at the beginning of the line below the list entry is
considered to end the list, so we get:

| * Project Participants
| \begin{description}
| \item[Rainer M Krug] \footnote{My email
| \end{description}
| }
| ORG-LIST-END-MARKER
| My address

Note how the description list is ended /inside/ the footnote
command.

Since LaTeX gobbles the trailing space in the footnote anyway, it
makes sense not to insert it in the first place, which this patch
does.  Your test case now exports correctly.

Cheers,

Lawrence
