[O] Export all headlines when some are set with :export:

[John Hendy]

Hello,


In creating a packing/buy list for an upcoming camping trip, I wanted
two exports:
- one for things to buy
- one for everything on the list for packing

My strategy was to tag things to buy with :export: (perhaps foolish,
but it was the obvious choice to selectively export them) to create my
shopping list. I'd also like an alternate export with all headlines in
the subtree exported.

Now the list is done like that, but I'm not sure how to export
everything without undoing all the tags on the buy list items.

I'm thinking I should have done something like a :buy: tag, then set
SELECT_TAGS to target those items, followed by removing that export
option and exporting as normal to get them all. Just thought I'd see
if there was a way to override the function of :export: as it
typically behaves.


Thanks,
John
