thanks a lot for this, both the reminder that filters can do this and
the provided function.  For sure, it works, and I'll be a happy user of
this.

In general:
If org-mode exports 'A' which I'd rather like to be 'B', then I can convert
'A' to 'B' after the export (e.g. via a filter).  It would be easier if it
was 'B' right away.  The support for short titles in LaTeX export might
be a general enough concept to be supported right away.  I guess, at
least a few people will add the identical snippet from above to their
.emacs right now...  So, why not have the above filter included and
active by default?
But don't take this too seriously.  For me the own filter solution works
great.  I already have a filter, that strips the #+XXX keywords from the
export, where I can easily add another filter function.  And the general
need for short titles has been surprisingly low, apparently.

So, thanks again,
Andreas
