Re: icalendar: exporting times of day specified in heading?

[Carsten Dominik <carsten.dominik@gmail.com>]

Hi Stephen,

while it might be possible to do what you ask for, I think it is error- 
prone because people might accidently have something in the headline  
which looks like a time.  I don't mind so much if Org's agenda  
stumbles over this, but I don't want to produce incorrect icalendar  
files.

Also, this icalendar export function is programmed in a messy way, and  
I don't see a quick way to fix this.

If you can make me a patch, I will take it.
