As I am a total newbie I will need to work out how to make that a
python file BUT as you have done the hard work it should be a lot
easier now.

It also looks like it might be close to being able to be used as a
regex string for something like NoteTab. Though, if using search and
replace, I would need to make it search for everything NOT matching
the above syntax and replace it with nothing.

I will also need to work out what "Closure cannot immediately follow
BegOfLine, EndOfLine or another closure" means, and fix it.

Many thanks for your help. :-)


Regards, John.
