[PATCH] Optional caption argument

["Thomas S. Dye" <tsd@tsdye.com>]

[-- Attachment #1: Type: text/plain, Size: 367 bytes --]

Aloha all,

The attached patches activate some dormant code that handles an  
optional argument to #+CAPTION:.  An example of use is also added to  
org.texi.

With these patches, Org-mode now recognizes a caption of the form:

#+CAPTION: [Short caption for list of figures]{Long caption for table  
(or link).}

and exports it properly to LaTeX.

All the best,
Tom
