Re: [PATCH] Preserve math environments in title when exporting to LaTeX

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

Aloha Richard and Carsten,

Thanks very much for this improvement.  Math appears to work as  
expected in the title and in figure captions.  I haven't noticed any  
adverse effects yet, but I've spent most of my time admiring the well  
typeset titles :)

All the best,
Tom
