Hello Rasmus,

thanks for you comment.  I try to explain my point of view better.  Now
the export to letter silently discard the headings text in the exported
tex.  This is quite bad, even if documented.  As a user I want to change
quite easily the export backend (text, latex, beamer, ...)  while
retaining most of my work.  Every backend as it's own supported
features, but discarding the input provided by the user does not provide
the best user experience to me.

By the way this patch does not change the final output, if there is no
section.lco available.  So there should be no regression and only
improvements.

I really prefer something that instead of discarding the user input
rewrite it to fit the backend features (if there is no heading/section
support, use something like the start of paragraph, and support section
only if enabled by the user) but this is beyond my coding abilities in
elisp, so I sent the minimal working patch with the minimal impact on
existing behaviour.

I guess this is another story.

I use org to touch as less latex as possible, I just downloaded the
section.lco and put in the same directory of my org file and everything
was working.  A little before I used apt-file search section.lco but
since nothing was found I quickly reverted to the manual download.  I
wish that everything is packaged as distro package, but I can survive
some manual work.

Best,
Daniele
