Bug: Exporting commands with angle brackets [6.34a]

Bug: Exporting commands with angle brackets [6.34a]

[Bill Jackson]

When exporting to LaTeX, curly brackets in a command will be escaped
if that command also contains angle brackets.  This can be a problem
when using beamer.  An example input file:

------------------------------------------------------------------------

#+LaTeX_CLASS: beamer

* The One and Only Frame
   When LaTeX \alert<2>{commands} contain angle brackets, the curly
   brackets are erroneously escaped in the output.  \alert{Commands}
   that do not contain angle brackets work properly.

------------------------------------------------------------------------

Typing C-c C-e l will generate the output file:

Hi Bill,

thank you for this report.  I have fixed this.  However, I do wonder  
if there might be cases where this will not work, for example with  
something like

\alpha<2>3

meant in a mathematical sense.  I find it hard to com up with an  
example where it really will fail, but we will have to see.
