Matthias,
I see the marker usage with sieve example. If you mark the set of words
with -foo2 where is the end of the marked area (as you may have X words
defined)? Is that the next new marker position? It means (wordlist):

bla bla -foo3 hello hello -foo2 happy happy -foo1
<-----------> <---------------> <--------------->  the area of marker

-foo2

bla bla -foo3 happy happy -foo1 
<-----------> <--------------->

or

bla bla -foo3 ...................happy happy -foo1 ??
<----------->                   <--------------->

My understanding is it works like a "file system" so a deleted -foo will
create a free space for new words - am I right?
As I uploaded lot of stuff for my naive experiments and the word list
is now very long so the way how the list is maintained seems to be a
challenge..
