Thanks everyone that came up with the solution!

I wish BBEdit would use the same regexp syntax as Perl! Of course it 
should be $1 -- I'm using BBEdit to edit Perl (which uses \1), 
sometimes I forget the differences... I was close to the solution 
(and as a newbie this makes me proud :-), but of course 
s/<#execute:(.*?)#>/\1/gee didn't work...

The correct regexp is:
s/<#execute:(.*?)#>/$1/gee

Lesson learned: use -w!
