[O] quote, quotation environments in org beamer export just comment text out.

[Ratish Punnoose]

Is there a reason that quote, quotation, verse, environments during export 
to tex just comment their contents.

As you can see, they precede the text with "%%"  which causes latex to 
ignore their contents.

This is an extract from ox-beamer.el

Thanks
Ratish
